Abstract:

O desenvolvimento de ligas de alumínio de propriedades mecânicas intermediárias possibilitou a extrusão de alumínio a participar de grandes mercados como a construção civil, transportes, automobilística, estruturas, entre outras. O conhecimento do processo de extrusão propicia o aumento de produtividade com melhor desempenho e precisão dimensional do produto acabado. Neste trabalho, procurou-se analisar as características de conformação de perfis sólidos das ligas de alumínio AA6063 e AA6082 com razão de extrusão (RE) variando de 2,0 a 27,8 e tubular com RE de 8,7. A partir da extrusão realiza

Abstract:

A indústria automotiva tem mostrado um crescente interesse pelas ligas de alumínio, em especial as ligas de alumínio da série 6xxx. Esta classe é amplamente empregada nas áreas de construção e de transporte, devido a sua boa resistência mecânica e excelente resistência à corrosão. No setor automobilístico sempre houve a necessidade de aprimoramento dos estudos do comportamento em fadiga, pois os componentes estruturais são submetidos a carregamentos vibratórios, esforços e tensões cíclicas e, como consequência, podem trincar e finalmente fraturar. A presença de um entalhe geralmente diminui a

Les besoins de réduction du poids se sont concrètement traduits par l'introduction de nouvelles nuances plus légères dans les structures automobiles. Ainsi, des alliages d'aluminium ont commencé à être intégrés dans les pièces de structure de plusieurs véhicules. La faible masse volumique des alliages d'aluminium (2,7g/cm 3 ) permet d'alléger le poids du véhicule qui entraîne une diminution de la consommation de carburant et, donc, des émissions de gaz à effet de serre. La striction et la rupture sont les principaux modes de défaillance qui entrainent le rebut systématique des pièces. C'est po

Abstract:

O uso das ligas de alumínio em aplicações estruturais tem crescido consideravelmente nas últimas décadas. Nos transportes, a baixa massa específica do alumínio resulta em uma alta razão resistência/ peso, favorecendo a fabricação de aviões, trens e automóveis. Com a crescente preocupação em reduzir a emissão de gases poluentes, vem tornando-se promissora a alternativa de reduzir o peso dos veículos substituindo peças convencionalmente produzidas com outros materiais por peças de alumínio. As ligas tratáveis termicamente da série 6xxx são frequentemente escolhidas para estas aplicações. Assim,

Magnesium (Mg) is a light-weight metal that has extraordinary physical and chemical properties for many potential applications in automobile, military, and electronics. Aluminum alloys, because of its light-weight, high strength and corrosion resistance have a wide range of commercial applications. Given these two, sometime competing, alloy systems, there are now many applications where the metallurgical compatibility of Mg- and Al-alloys are required for engineering applications. One such case is the development of diffusion barrier for U-Mo metallic fuel in Al-alloy cladding, where Mg, with

Abstract:

Extruded profiles of AlMgSi-alloys are widely used in various industries such as the automotive industry, aerospace and in the oil and gas industry. To tailor the alloys for specific needs and applications, more information about the behaviour of alloying elements is needed. In this study, extruded profiles of AA6082 have been examined. Seven different alloys with increasing content of Mn have been subjected to three homogenisation procedures. The purpose of the different homogenisation procedures was to obtain different densities of dispersoids, while still maintaining the same level of eleme

Abstract:

AA6061 Al alloys modified with addition of Mn, Cr and Cu were homogenized at temperatures between 350 ºC and 550 ºC after casting. STEM experiments revealed that the formation of α-Al(MnFeCr)Si dispersoids during homogenization were strongly affected by various factors such as heating rate, concentration of Mn, low temperature pre-nucleation treatment and homogenization temperature. Through analysis of the STEM results using an image software Image-Pro, the size distributions and number densities of the dispersoids formed during different annealing treatments were quantitatively measured.

Abstract:

There is a current trend in increased use of aluminum extrusion alloys in automotive applications. This trend is driven by the need to reduce the vehicle weight, which in turn, is to decrease energy use and/or emissions of the vehicles. In this work, Al-Mg-Si alloys, and especially variants of AA6082 with different Mn and/or Cr additions have been studied. The objectives of the study are to i) experimentally characterize the evolution of the constituent particles (phase, volume fraction and size) and dispersoids (chemistry, crystal structure, size and volume fraction), ii) rationalize the me

Abstract:

Nel seguente elaborato si propone lo sviluppo di un modello agli elementi finiti (FEM) del processo di friction welding del quale, attraverso i dati rilevati da prove sperimentali di validazione termica, vengono valutati i parametri ottimali di simulazione. Ai risultati così ottenuti vengono applicati anche algoritmi per la valutazione della microstruttura e della qualità della saldatura, sviluppati originariamente per l'analisi dell'estrusione: in entrambi i casi a seguito del confronto con le analisi metallografiche dei provini è stato possibile validare ulteriormente il modello creato.

Abstract:

Automotive and aerospace industries consume a significant amount of Al alloys in structures and framing. There is, however, a significant challenge to join the alloy components by laser welding. A key problem is the presence of large amount of porosity in the welds. This research work aimed to understand factors affecting porosity formation in laser welding of AA6014 Al alloy and identification and verification of a suitable method for the porosity reduction and elimination. AC-170PX (AA6014) Al alloy was welded, for the first time, using a 5 kW disk laser in two different configurations: fill

As propriedades mecânicas e metalúrgicas de uma junta soldada devem ser minuciosamente estudadas para que se possa qualificá-la para aplicação em engenharia. Assim, com o desenvolvimento de novos processos de soldagem torna-se necessário um estudo detalhado para determinação destas propriedades. Este é o caso da soldagem por Fricção e Mistura Mecânica (Friction Stir Welding) em que, ao contrário das outras técnicas convencionais, a temperatura de fusão do material não é atingida durante o processo. Com isto, vários problemas que são relacionados às altas temperaturas desaparecem e, além disto,

This thesis systematically investigates the effects of a recently developed modified ageing procedure of aluminium alloys, termed the T6I6 temper, on the microstructural development and mechanical properties of the Al ??? Mg ??? Si - Cu alloy 6061. For the T6I6 temper, a conventional single stage T6 temper is interrupted by an ageing period at a reduced temperature (65??C) to facilitate secondary precipitation, before resuming the final ageing at the temperature of the initial T6 treatment. The T6I6 temper was found to cause simultaneous increases in tensile properties, hardness, and toughness

This technique is capable to join many engineering materials but was initially focused on high strength aluminum alloys (series 2XXX, 6XXX and 7XXX) due to two main approaches: because they are difficult to weld by conventional welding processes fusion for their applications in key sectors such as automotive, aviation,
