Article dans une revue avec comité de lecture(Springer, 2021)The use of shape memory alloys for micro-actuators constitutes a field of application in which copper-aluminum-based alloys find their usefulness because they can reach higher activation temperatures and are easier to ...
-
Article dans une revue avec comité de lecture(Frontiers Media SA, 2021)The objective of this study was to develop a thermo-mechanical strategy to create a radial elasticity gradient in a β metastable Ti-Nb-Zr alloy, and to characterize it in terms of microstructural and mechanical properties. ...

CHALAL, Hocine; ABED-MERAIM, Farid (CIMNE, 2017)
In this work, ductility limits of metallic materials, associated with the occurrence of strain localization, are predicted using the GTN damage model coupled with bifurcation theory. The resulting approach is implemented ... -
Article dans une revue avec comité de lecture;BERVEILLER, Sophie; MERAGHNI, Fodil; ; (Springer Science and Business Media LLC, 2021)
In this work, a (TiHfZr)(NbTa) 26 (%at) high-entropy quinary alloy has been developed especially for high-temperature superelastic applications and studied over a large range of temperatures. The mechanical properties of ...

In this paper, forming limit diagrams (FLDs) for an aluminum alloy are predicted through numerical simulations using various localized necking criteria. A comparative study is conducted for the FLDs determined by using the ...
