Book excerpt: Aluminium is a well established modern lightweight engineering and functional material with a unique combination of specific properties like strengh, formability, durability, conductivity, corrosion resistance, etc. It is present in many intelligent solutions in established markets like building, transport, packaging, printing, and many others, in our fast moving modern society. The various aluminium alloys can be processed quite efficiently in large quantities by conventional fabrication routes, as well as in special sophisticated forms and material combinations for highly innovative high–tec solutions and applications. This book contains latest information about all these aspects in form of the refereed papers of the II th International Conference on Aluminium Alloys "ICAA", where world–wide experts from academia and engineers from industry present latest results and new ideas in fundamental as well as applied research. Since 22 years the ICAA series provides scientists and engineers with a complete overview over the latest scientific and technological developments, featuring profound technology–based overviews and new innovative perspectives. This book is a reference for the scientific community as well as for the aluminium industry working on aluminium alloy development, processing and application issues. It gives a global perspective on the current focus of international research with emphasis on in–depth understanding of specific properties and applications of conventional and advanced aluminium alloys.

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The age-hardening AA2198 alloy is mainly used in aeronautic applications. The anisotropic T1 - Al2LiCu phase gives the main contribution to strengthening in this system. The main objective of this study is to understand the strengthening mechanisms in terms of interactions between the dislocations and the T1 plate-like precipitates. The first step consists in the development of a characterization procedure adapted to the T1 phase (characterization of the diameter, thickness and volume fraction of the T1 plates). The thermo-mechanical treatment is adapted in order to vary the T1 parameters independently and the yield strength evolution is systematically measured and that permits the investigation of the relationship between the T1 microstructure and the yield strength variations. The experimental data base that is generated allows testing and improving the existing yield strength models. An energetic approach of the shearing mechanisms is used to model precisely the yield strength evolution for a high number of microstructures. The decrease in yield strength after the peak is solely explained by invoking the shearing mechanism. The investigation of the plasticity phenomenon associated to the T1 phase, with the study of the shear bands and of the work hardening behavior, is the last step of this work. A shearing-to-by-passing transition is found to occur for long-over ageing times.

This book was released on 2008 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: L’objectif de ce travail de thèse est de caractériser les propriétés mécaniques et analyser les mécanismes d’endommagement des alliages de cuivre à durcissement structural Cu-Ni-Si qui peuvent être utilisés dans la construction des cages d’écureuil des moteurs asynchrones. Une attention particulière est attachée à l’influence de l’exposition en température associée à la zone affectée thermiquement lors du brasage. Cette exposition provoque essentiellement une évolution de l’état de précipitation, qui est étudiée par MET. Dans l’alliage Cu-Ni-Si nous observons une augmentation de la taille des précipités Ni2Si, alors que l’état de précipitation évolue de façon plus complexe dans l’alliage Cu-Cr-Zr. Le comportement sous traction à rupture à différentes températures avec différentes vitesses de sollicitation a été étudié pour les deux alliages sous différents états. Le résultat montre que Cu-Ni-Si à l’état de réception présente un comportement anormal typique de la fragilisation dynamique avec une rupture fragile intergranulaire. Ce phénomène de fragilisation dynamique disparaît lorsque le matériau subit une exposition en température conduisant à un état “ sur-revenu ”. il n’apparaît pas non plus dans Cu-Cr-Zr. Nous avons dérivé de la littérature un modèle fondé sur la ségrégation intergranulaire d’un élément fragilisant. Celui-ci nous permet d’expliquer l’ensemble des résultats de façon qualitative ou quantitative. L’intervention de la fragilisation dynamique est aussi mise en évidence sous chargement cyclique pour Cu-Ni-Si. Dans ce cas, la contrainte moyenne positive joue le même rôle que celui de la contrainte de traction et chargement monotone
