Abstract:
The 6xxx series alloys are well known for desirable combinations of high strength, weldability, corrosion resistance and formability. This paper investigates the influence of chemical composition on the solution heat treatment parameters of rheo-high pressure die cast (R-HPDC) 6xxx series aluminium alloys. The presence of copper in the 6xxx series aluminium alloys affects the solution heat treatment by promoting incipient melting. The incidence of incipient melting is investigated for the R-HPDC alloys using Differential Scanning Calorimetry (DSC) and optical microscopy. R-HPDC is known to produce surface liquid segregation and centre-line liquid segregation when processing the alloys and these areas are the most susceptible to incipient melting. The applicability of single and multiple step solution heat treatments are investigated. The alloys used for this study include the Cu-free alloy 6082, as well as the Cu-containing alloys 6013 and 6111.

Abstract:
Microstructural evolution of 6xxx Al alloys during various metallurgical processes was analyzed using accurate thermodynamic database. Phase fractions of all the possible precipitate phases which can form in the as-cast and equilibrium states of the Al-Mg-Si-Cu-Fe-Mn-Cr alloys were calculated over the technically useful composition range. The influence of minor elements such as Cu, Fe, Mn, and Cr on the amount of each type of precipitate in the as-cast and equilibrium conditions were analyzed. Phase fraction diagrams at 500 ?C were mapped in the composition range of 0-1.1 wt.% Mg and 0-0.7 wt.% Si to investigate the as-homogenized microstructure. In addition, phase fraction diagram of Mg2Si at 177 ?C was mapped to understand the microstructure after final annealing of 6xxx Al alloy. Based on the calculated diagrams, the design strategy of 6xxx Al alloy to produce highest strength due to Mg2Si is discussed.

Abstract:
The effect of the chemical composition, i.e. content of silicone (Si) and other alloying elements (Zr, Mn, etc) on the corrosion behaviour and mechanical properties of Al-Mg-Si (6xxx) type alloys was investigated in this paper. Open circuit corrosion potential (OCP) measurements, linear polarization and potentiodynamic anodic/cathodic polarization were employed in order to determine the corrosion behaviour of artificially aged Al-Mg-Si samples in the chloride ions containing aqueous corrosion solutions. The difference in OCPs for the tested 6xxx type alloys in relation to the standard AA1020 alloy was observed to be between 1-4%, except for the AlMg0.65Si0.76Zr0.1 alloy when the difference was 14% (about 100 mV). The presence of zirconium and manganese in AlMgSi0.7 base alloy, that contains small excess of Si, shifts the OCPs to more negative values for -15 mV (~2%) and -88 mV (~11%) in natural water and 0,51 mol NaCl, respectively. All the tested 6xxx type alloys, except AlMg0.7Si1.2Mn0.8, show almost the same corrosion rates and other corrosion characteristics in chloride solution, with mass loss per year between 2.3-3 g/m2 .

Abstract:
In high strength AlMgSi alloys additions of Mn and Cr lead to the formation of dispersoid phases whose primary functions are to improve fracture toughness and control grain structure. Whether or not dispersoid phases form during heating to the homogenisation temperature and which dispersoid forms is strongly dependent on the alloy composition. By correlating dispersoid features after different homogenisation heat treatments to TEM investigations into the crystal structure, it is proposed that the crystal structure and chemical composition of the dispersoids changes as the dispersoids coarsen at increased temperatures and times.

Associated microstructural changes of characteristic states of examined alloys were studied by using the transmission electron microscope (TEM). The results show that the stress level decreases with increasing deformation temperature and deformation rate. And was also found that the activation energy Q strongly depends on both, the temperature and rate of deformation.

Mestrado em Engenharia de Materiais
O presente trabalho teve como principal objetivo o estudo da homogeneidade de biletes de ligas de alumínio das séries 6060, 6061, 6063 e 6082, usadas pela empresa Extrusal. O estudo foi realizado sobre amostras recebidas de diferentes fornecedores, recorrendo a ensaios de microdureza de Vickers e análise microestrutural por microscopia eletrónica de varrimento (SEM) e microscopia eletrónica de transmissão (TEM). Relativamente a trabalhos anteriores sobre materiais semelhantes, conseguiu-se melhorar de forma substancial a preparação de amostras para observação microestrutural, o que se saldou no acesso a detalhes de informação até agora inacessíveis. Inicialmente foi dada especial atenção a defeitos em biletes. Observaram-se pela primeira vez defeitos tipo camada de refusão e/ou segregação inversa num bilete da série 6061. Para um bilete da liga 6082 encontraram-se diferenças microestruturais compatíveis com os defeitos referidos anteriormente, mas menos óbvias. Nas restantes ligas não se encontrou evidência para este tipo de defeitos. A presença de segundas fases (principalmente de AlFeSi), normalmente com a forma de partículas alongadas presentes nas fronteiras de grão da matriz de Al, é evidente na generalidade dos materiais antes da extrusão, sugerindo homogeneização incompleta. Nos casos agora estudados foi confirmado o arredondamento destes precipitados quer por tratamento térmico simples quer por efeito termomecânico durante a extrusão. Foi também identificada a presença de precipitados no interior dos grãos em algumas ligas, o que permite sugerir estar-se na presença de diferentes condições iniciais de homogeneização. Contudo, não se detetou a presença de precipitados de Mg2Si, o que permite admitir que as ligas se encontram em condições adequadas para o posterior endurecimento por envelhecimento artificial. Em geral, as posições próximas da face exterior dos biletes apresentaram durezas ligeiramente inferiores ao interior do bilete, por efeito provável das diferentes velocidades de arrefecimento das distintas regiões do bilete, quando do seu fabrico. Simulou-se ainda um percurso térmico para testar a influência do tempo e da temperatura (na espera que antecede o acesso do bilete ao processo de extrusão) nas propriedades do perfil extrudido. Através da análise das microestruturas e da dureza de algumas amostras verificou-se que diferentes ligas evidenciam sensibilidades diferentes em relação a esta espera. Globalmente, nenhuma liga exibiu evidência de condicionantes sérias relativamente à eficácia dos processos padrão de extrusão e envelhecimento artificial.
The goal of the present work was to study the homogeneity of billets from aluminum alloys of series 6060, 6061, 6063 and 6082, used by the company Extrusal. This study was conducted on samples received from different suppliers, using Vickers microhardness tests and microstructural analysis by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). With respect to previous work on similar materials it was possible to substantially improve the preparation of samples for microstructural observation, which resulted in accessing details yet undisclosed. Initially, attention was given to defects in billets. A re-melted and/or inverse segregation layer was observed for the first time in a billet from series 6061. Alike microstructural differences were also found in a billet of series 6082, coherent with this type of defects, but not as clear. There were no similar findings in the remaining billets. The presence of secondary phases (mostly AlFeSi), usually consisting of elongated particles along the grain boundaries in the aluminum matrix, was evident in most materials before processing, suggesting incomplete homogenization. In the present study, due to simple thermal treatment or combined thermomechanical treatment during extrusion, a clear rounding of these particles could be noticed. Small particles of secondary phases were also found within the grains of some alloys, suggesting distinct homogenization conditions in distinct alloys. However, there was no evidence for the presence of Mg2Si precipitates, which means that these alloys are presumably in adequate conditions to proceed to artificial ageing with hardening. In general, the billets hardness close to the outer surface was slightly lower than in the interior of the billet, as a likely consequence of distinct cooling rates while forming the billet. Simulated thermal routes were tested in order to check the influence of the billet waiting time and temperature before extrusion on the properties of the extruded profile. Through the analysis of microstructures and hardness of these samples it was found that different alloys show different sensitivities to this waiting period. In general, none of the alloys exhibited any evidence for constraining factors inhibiting the efficacy of the standard extrusion and artificial ageing processes.

Abstract:

The present work has been carried out in order to investigate Al-Mg-Si alloys that are deformed at moderate temperatures. These temperatures are in the range between 200 C and 300 C. Also some experiments are performed at room temperatures. Two deformation models have been applied in the experiments: material deformation by compression testing and by forward extrusion.

The investigated alloys are AA6063, AA6082 and an alloy that is named “Alloy R” in this work. The latter alloy is the industrial alloy AA6082 without the Mn-addition (0.56wt%Mn in the AA6082). The “R” denotes the recrystallized microstructure in the material after hot forming operations.

The investigations show the effect of changing the temperature in the given temperature interval on the stress-strain relationship for each alloy. From the compression testing, it is found that none of the alloys AA6063 or Alloy “R” reaches a steady state condition as true strain approaches 0.8 for deformation temperatures between 200 C and 250 C. At compression testing performance at 300 C, the alloy “R” reaches a steady state condition at a true strain equal to 0.4.

As true stress-true strain relationship has been investigated for the “Alloy R” and the AA6063 at comparable deformation parameters, it is shown that the alloy “R”, with the highest Si-content, requires the highest true stress for a given true strain value (AA6063: 0.45wt%Si, Alloy “R”: 0.87wt%Si).

From the compression testing, the effect of Mn on the material properties in the AA6082-alloy has been determined. For the Alloy “R” and the AA6082, the true stress reached the same value after a certain amount of deformation. As deformation temperature increases, this common value of true stress corresponds to a decrease in true strain.

The AA6082 and Alloy “R” are also compared in experiments performed in forward extrusion. One observes that for the same deformation temperature and at identical die diameters, the ram force is identical. It is worth noticing that these alloys did not show the same relationship during the compression testing at low values of true strain (<0.8). On a microscopic scale, one concludes that Mn has no significant effect on the stress-strain relationship for the applied deformation parameters in the forward extrusion equipment.

Hardness measurements indicate that the age hardening potential in the extruded test specimen decreases as the deformation temperature increases. The hardness data is similar for both the AA6082 and the Alloy R, thus indicating that the Mn content has no significant effect on the strength of the material.

The deformed material has been annealed in order to investigate the recrystallization process in the AA6082 and the Alloy “R”. The recrystallization grain size in the Alloy “R” is significantly larger than in the AA6082 at comparable deformation parameters after annealing at 530 C for 15 minutes. This result is due to the effect of Mn-containing dispersoids in the AA6082. The recrystallization grain size in the Alloy “R” seems to be unaffected by the deformation temperature after annealing for 15 minutes. The observation of the AA6082 is quite different. A small increase in grain size is observed for both reduction ratios as the deformation temperature is elevated from 20C to 200 C and further to 250 C. At extrusion temperatures of 300 C the recrystallization grains are significantly larger.

Annealing experiments performed at 430 C on the AA6082 indicates that a change in the deformation temperature from 200 C to 250 C does not affect the amount of stored energy in the material significantly.

The Forge2 programme has been used to perform numeric simulations of the forward extrusion experiment. From this the temperature distribution, strain rate variation and true strain development in the test piece had been investigated. As the simulated true strain values are compared to the grain size in the annealed material, the recrystallization grain size is related to the amount of stored energy in the material in a very convincing way. It is also shown that the recrystallization grain diameter is related to the amount stored energy as the grain diameter is investigated in the radial and the extrusion direction separately.

Abstract:
Les alliages d’aluminium, présentant un rapport résistance-poids élevé, sont capables de répondre aux exigences de réduction de masse et d’augmentation de sécurité dans la construction de nouveaux véhicules. Cependant, lors des opérations d’emboutissage, ces alliages présentent une plus faible formabilité et un retour élastique plus élevé que les aciers traditionnellement utilisés. L’emboutissage à température moyenne (qualifiée de tiède) apparaît comme une solution très intéressante pour résoudre ces problèmes. Néanmoins, l’emboutissage pour les alliages d'aluminium de la série 6000, reste toujours un défi car la gamme de température utilisée est proche de celle utilisée lors des traitements thermiques de ces alliages. Ainsi l’augmentation de la température peut entraîner un durcissement par précipitation. En outre, ces alliages sont susceptibles de vieillir naturellement. Tous ces changements doivent être prédits pour éviter des variations dans le process de production. Dans ce contexte, l'objectif principal de ce travail a été d'analyser les conditions d’emboutissage à tiède de deux alliages d’Al-Mg-Si (l'EN AW 6016-T4 et l'EN AW 6061-T6), afin de d’améliorer la robustesse des opérations d’emboutissage. Des essais de traction et des essais d’emboutissage de godets cylindriques en température ainsi que des mesures de retour élastique (essai dit de Demeri) ont été effectués. Plusieurs paramètres comme le vieillissement naturel, la durée de chauffe et la vitesse d’emboutissage ont été étudiés afin de proposer des solutions permettant d’améliorer la robustesse des opérations d’emboutissage. L’emboutissage à tiède se révèle être une solution efficace pour améliorer la formabilité, réduire le retour élastique et la variabilité causée par le vieillissement naturel. Cependant, utiliser des vitesses d’emboutissage élevées et une chauffe rapide sont nécessaire pour éviter le durcissement par précipitation pendant l’emboutissage
Heat treatable aluminum alloys present a high strength-to-weight ratio, which replies to the requirements of mass reduction and safety increase in the construction of new vehicles. However, in sheet metal forming operations, these alloys have lower formability and higher springback than traditionally mild steels used. In this context, forming in warm temperature appears as an attractive solution to solve these problems. Nevertheless, there is still a challenge since the temperature range used in warm forming is similar to one used in the heat treatment of these alloys. Thus increasing the temperature can lead to precipitation hardening, which modifies the thermo- mechanical behavior of the material. In addition, these alloys are prone to natural aging that causes variability in forming operations and increases the amount of scrap. The present study addresses the warm forming of two heat-treated Al-Mg-Si alloys (EN AW 6016-T4 and EN AW 6061-T6), in order to propose solutions that can contribute to the increase of robustness of sheet metal forming operations. The influence of natural aging, temperature and exposure time has been studied by using uniaxial tensile tests, cylindrical cup tests and the split ring tests. The main goal is to propose solutions to improve the robustness of the sheet metal forming process. Warm forming proves to be an effective solution for improving formability, reducing the springback and variability caused by natural aging. However, high forming speeds and fast heating are necessary to prevent precipitation hardening during forming operations

Pour la réalisation des structures aéronatiques en alliages d’aluminium, le soudage par friction malaxage offre des perspectives intéressantes, de par sa capacité à assembler les matériaux à l’état solide.

Cette étude est consacrée au cas particulier des joints soudés par friction malaxage d’alliages d’aluminium de la série 6xxx. La caractérisation expérimentale des évolutions microstructurales et du comportement mécanique associé aboutit à une meilleure compréhension de l’abattement des propriétés en traction des soudures. Les outils de modélisation développés permettent de décrire les relations entre les paramètres du procédé, les évolutions de la précipitation fine et le comportement en traction des assemblages.

For the assembly of aeronautical structures made of aluminium alloys, Friction Stir Welding offers new interesting possibilities, due to its ability to joint materials at the solid state. As no solidification defect are formed, the microstructure resulting from welding plays a major role in the properties of the weld. This study is dedicated to the particular case of friction stir welds of aluminium alloys from the 6xxx series. The experimental characterization of the microstructural evolutions and of the resulting mechanical behaviour provides a better understanding of the drop in the tensile properties of the welds. Modelling tools have been developed to describe the relationship between the process parameters, the evolutions of the hardening precipitation and the tensile behaviour of the joints. Finally, they are used to define some ways of optimization of the friction stir welds

Abstract:

Two different solution heat treatments (2hours at 570ºC and 10minutes at 520ºC) have been used to study precipitation in two 6xxx (Al-Mg-si) dispersoid-freealloys with composition: 0.721 at % Si, 0.577 at % Mg (alloy A3) and 0.57 at %Si 0.72 at % Mg (alloy A12). The relation between their microstructure and macroscopical properties such as hardness and ductility has been investigated. Tensile tests, hardness measurements, electrical conductivity sigma tests, grain size measurements in optical microscope and microstructure characterization in Transmission Electron Microscope (TEM) have all been done. The effect of alloy composition and solution heat treatment temperature and time on the microstructure and the resulting macroscopical properties (hardness, yield stress, tensile strength and ductility) was investigated. The results indicate that when alloy A3 is solution treated at 520ºC for 10 minutes and then annealed for 3 hours at 175ºC, its hardness, yield stress and tensile strength as well as ductility is optimised i.e.A3 has better mechanical properties and low cost of production at these conditions. It has been proved that the strengthening was solely due to precipitation particles and not grain size.

Les séquences de précipitation d'alliages d'aluminium à durcissement structural appartenant aux séries 2XXX (Al-Cu), 6 XXX (Al-Mg-Si-(Cu)) et 7 XXX (Al-Zn-Mg-(Cu)) ont été étudiées par microscopie ionique et sonde atomique tomographique. Cet instrument permet de caractériser les matériaux métalliques avec une résolution subnanométrique et d'établir des cartographies tridimensionnelles des différents éléments dans le volume analysé. Nous avons déterminé les compositions des zones de Guinier-Preston et des phases stables et métastables formées lors des traitements de vieillissement à la température ambiante et lors de revenus de type industriel. Nous avons montré que les zones gp, en forme de disques monoplans riches en cuivre, de l'alliage Al-1,7 à T. % Cu admettent une certaine variabilité de compositions, entre 50 et 100 à T. % Cu. Les zones GP formées dans les alliages 6 XXX et 7 XXX étudies se présentent sous formes d'amas diffus de solutés (Mg et Si pour la série 6XXX Zn et Mg pour les 7XXX). Ces zones GP contiennent une proportion importante d'aluminium (de 75 à 80 at. % en moyenne). Les compositions des phases métastables (alliages 6xxx) et (alliages 7XXX) s'écartent notablement des compositions stœchiométriques prêtées aux phases stables Mg2Si et MgZn2 des diagrammes d'équilibre. La phase des alliages Al-Zn-Mg-(Cu) ne correspond pas non plus à la stœchiométrie attendue, tant par l'existence d'une teneur non négligeable en aluminium que par son rapport Zn/Mg, inférieur à 2. Nous pensons que la composition de la phase, telle qu'elle est caractérisée par les techniques de diffraction (RX et MET), est susceptible d'évolution au cours du revenu (température, nombre de paliers,), en particulier en fonction de son mode de formation. Ce peut être par transformation directe de la phase transitoire, et alors montre une grande similitude avec la composition de, ou par germination (sur ou autres enrichissements locaux de la solution solide) et alors la composition de apparaît plus proche de la stœchiométrie attendue. Dans l'alliage quaternaire, le cuivre participe à la composition des phases et et apparait, en comparaison avec l'alliage ternaire jumeau, favoriser la persistance des premiers stades de l'évolution de la cinétique. L'ajout de cuivre à l'alliage 6xxx ternaire que nous avons étudié augmente de façon spectaculaire la densité et la fraction volumique de la phase durcissante.

Abstract:
Insufficient formability can be a major issue in the manufacturing of complex parts, particularly in aluminum alloys that have less formability when compared to steel. The approach which is the subject of this work is to determine the technical feasibility of partial forming, followed by a fast heat treatment and then further deformation. Alloys for consideration would include both 5xxx and 6xxx alloys typically used on interior and exterior automotive panels. The heat treatment regimes used for 6xxx alloys did not affect the material structure, which was confirmed by microstructural analysis and comparison of mechanical properties before and after the heat treatment. Experiments on 5xxx alloys indicated relative improvement of 300% or more. Regimes of material deformation and heat treatment will be presented.
