Full textThis study aims to determine the influence of iron and manganese in an aluminum alloy with 9% silicon (% by weight). Were prepared two families of alloy Al-9%Si: one with the content of 0.1%, 0.4%, 0.8% and 1.2% Fe and a second alloy of Al-9% Si-0,8%Fe content of 0.1%, 0.4% and 0.7% Mn. For this study, tensile specimens were produced in permanent mold casting according to ASTM B108. The specimens obtained were pulled for quantitative evaluation of the mechanical properties and were subjected to a qualitative metallographic evaluation. Qualitative analysis of the bodies of tensile fracture test was conducted in order to compare the effect of additions of Fe and Mn. The effect of incremental addition of Fe in the alloy Al-9% Si was observed in the tensile test that showed a decrease in both the tensile and elongation flow as resulting from the formation of β-Al5FeSi phase platelet morphology showed that interrupting the continuity of aluminum matrix. To levels below 0.4% Fe, there was a slight increase in strength can be attributed to the formation of α-Al8Fe2Si phase morphology presented in chinese script that does not interrupt the continuity of the matrix. With addition of increasing concentrations of Mn in the alloy Al-9% Si-0, 8% Fe was an increase in the tensile strength and elongation but fall of yield stress when compared to the same alloy without Mn addition. We conclude that this behavior can be attributed to a change in morphology of the intermetallic platelets to chinese writing interspersing the ductile matrix with brittle phase due to the addition of Mn.

Full textThe instructions of the European Union pilot the R&D in the automotive industry regarding the use of lightweight materials which aims at reducing fuel consumption and emission of exhaust gases.The objective is to develop steels of density reduced by at least 10% (ρmax ≈ 7g/cm3). Iron aluminum alloys display promising physical and mechanical properties but they often exhibit surface defects, referred to as roping, appearing after the deep drawing process. This study was carried out to better understand the conditions of recrystallization during hot rolling to control the microstructure and thereby limit these defects.During hot deformation, it is generally agreed that geometric dynamic recrystallization (GDRX) and continuous dynamic recrystallization (CDRX) operate in ferritic alloys with high stacking fault energy. In this study, the existence of a transition between CDRX and the mechanism of discontinuous dynamic recrystallization (DDRX) has been brought into evidence in the temperature range 900 1100°C and strain rate range 0.1-50s-1. Post-dynamic recrystallization was also studied to observe the evolution of microstructure during holding temperatures.A model formerly developed for the CDRX of aluminum was then used to simulate a rolling pass. Comparison of computed and experimental results shows some differences but this model can reproduce microstructural changes qualitatively

Full textIn the last few decades significant efforts have been made in modeling ductile failure processes resulting in substantial progress. However, the full understanding of ductile failure mechanisms under specific stress states still remains an open question. This is partly due to missing experimental data and validation of models for such loading conditions.In this work, data acquisitions are mainly obtained by using laminography, which makes the imaging of regions of interest in flat samples possible. The use of large (and thin) specimens allows various stress states and engineering-relevant boundary conditions to be generated, which could not be assessed in three dimensions and in-situ at micrometer scales before. Digital Volume Correlation (DVC) is used for measuring displacement fields in the bulk of samples by registering 3D laminography images. Two material classes that are representative of two generic modes of ductile failure have been examined, namely, Al-alloys (failure by instability) and cast iron (failure by void growth and coalescence). The observation of microstructure and strain-damage interactions at micrometer resolution for various specimen geometries and associated levels of stress triaxiality are studied for Al-alloys. Additionally, a combined computational-experimental (DVC-FE) framework is introduced to validate numerical simulations at the microscopic scale for nodular graphite cast iron. Finite Element (FE) simulations, which account for the studied material microstructure, are driven by Dirichlet boundary conditions extracted from DVC measurements.Last, the DVC-FE framework is upgraded to an integrated identification procedure to probe elasto-plastic constitutive law of the cast iron ferritic matrix not only in terms of kinematic fields induced by the random microstructure but also by overall load levels

Full textThis thesis presents information on the development and processing of potentially low-cost α+β Ti-Al-V-Fe alloys. The major problem addressed in this research is the high cost of titanium and its alloys which have limited their widespread use since commercial production began in the 1950s. Two cost reducing research approaches: substitution of low-cost for expensive alloying elements, and the optimisation of hot working parameters were adopted in the development and processing of the low-cost Ti-Al-V-Fe alloys. In the first approach, two sets of low-cost alloys were developed based on the composition of commercial grade Ti-6Al-4V, the most utilised titanium alloy. The first set of alloys were designed by partial and full substitution of expensive vanadium with iron, a low-cost beta stabiliser, producing Ti-6Al-3V-1Fe, Ti-6Al-2V-2Fe, Ti-6Al-1V-3Fe and Ti-6Al-4Fe alloys. The second set of alloys was designed by both partial replacement of vanadium with iron and the reduction of aluminium content from 6 to 4.5 wt%, producing: Ti-4.5Al-3V-1Fe, Ti-4.5Al-2V-2Fe and Ti-4.5Al-1V-3Fe alloys. The influence of varying composition on the microstructure, hardness and corrosion behaviour was evaluated. Thermo-Calc software with the TTTi3 database was used to determine the phases present, their relative amounts and transformation temperatures under equilibrium conditions. The alloys were then produced by vacuum arc melting. The microstructure and hardness of as-cast samples and annealed samples of each alloy were evaluated. The results from the Thermo-Calc modelling showed that the beta transus temperature of the alloys reduced with increasing iron content while the volume fraction of the beta phase increased with increasing iron content. When compared to wrought Ti-6Al-4V alloy, the iron-containing alloys had a lower transus temperature but a higher volume fraction of beta phase. The annealed alloy showed a reduction in the volume fraction of beta phase since there was sufficient time for the beta-alpha transformation to take place during annealing. The hardness of iron-containing alloys increased with increasing iron content in both as-cast and annealed conditions. The hardness of the wrought Ti-6Al-4V alloy was lower than all the iron-containing low-cost alloys except Ti-4.5Al-3V-1Fe. The annealed samples were harder than the as-cast alloys. The increase in hardness was attributed to the Fe content, reduction in lath thickness and oxygen contamination during casting and heat treatment. The corrosion behaviour of the annealed iron-containing alloys were compared with the wrought Ti-6Al-4V alloy in solutions of sulphuric acid, sodium chloride and mixed sulphuric acid /sodium chloride. Open circuit potential and linear polarisation measurements were carried out. Ti-6Al- 1V-3Fe and Ti-4.5Al-1V-3Fe alloys had superior corrosion resistance to commercial Ti-6Al-4V in both sulphuric acid and sodium chloride solutions. Cost analysis on the low-cost alloys showed that about 7% ($175.6/100 kg) lower cost savings can be achieved by replacing 3 wt% V with Fe in Ti-6Al-4V. The advantage of cost with the improved hardness and corrosion resistance was used as a basis for selecting Ti-6Al-1V-3Fe and Ti-4.5Al-1V-3Fe for further work, i.e. optimisation of hot working parameters as the second cost reducing approach. In the second approach, the two selected experimental alloys were machined to rectangular samples and subjected to isothermal compression testing at varied temperatures (750 - 950°C) and strain rates (0.001 - 10 s-1) on a Gleeble 3500 thermomechanical simulator. The analysis of stress-strain curve and processing maps were used to determine the optimum processing condition during hot working. The activation energy for hot working of the alloys was determined using the hyperbolic-sine constitutive equation. The commercial grade Ti-6Al-4V alloy with a complex initial microstructure was also investigated. The flow curves exhibited distinct features under different deformation conditions. This indicated that flow behaviour is dependent on process variables such as strain rate, deformation temperatures, total strain and initial microstructures. Processing maps showed that the optimum processing conditions for the Ti-6Al-4V, Ti-4.5Al-1V-3Fe and Ti-6Al-1V-3Fe alloys were ~940°C/1 s-1, ~900°C/0.1 s-1 and ~900°C/0.01 s-1 respectively. Microstructural analysis revealed that the dominant softening mechanisms at the identified optimum processing conditions in both Ti-6Al-1V-3Fe and Ti-4.5Al-1V-3Fe alloys were dynamic recrystallisation of the prior beta grains and dynamic globularisation of the alpha phase respectively. Dynamic globularisation occurred much faster and easier in the lower aluminium alloy Ti-4.5Al-1V-3Fe (0.1 s-1) than in the Ti-6Al-1V-3Fe alloy (0.01 s-1). The activation energy for hot working of the alloys was higher in Ti-6Al-4V and Ti-6Al-1V-3Fe than in Ti-4.5Al-1V-3Fe. Some of the regions of instability were identified as ≥ 935°C/0.05 - 0.1 s-1 for Ti-6Al-4V, 750 - 780°C/1.2 - 10 s-1 for Ti-4.5Al-1V-3Fe and 750 - 870°C/0.9 - 10 s-1, Ti-6Al-1V-3Fe. The microstructures of the samples deformed in these regions revealed non-uniform deformation, voids and cracking as the unsafe softening mechanisms. These regions should be avoided when processing the alloys to save cost and prevent waste of materials.
