This article deals with the application of several X-ray and neutron diffraction methods to investigate the mechanics of a stress induced martensitic transformation in Cu-based shape memory alloy polycrystals. It puts experimental results obtained by two different research groups on different length scales into context with the mechanics of stress induced martensitic transformation in polycrystalline environment.
Cet article résume une série de travaux où les grands instruments (tels que la diffraction de neutrons et de rayons X du rayonnement synchrotron) ont été appliqués à lʼétude de la transformation martensitique induite par la contrainte, dans le cas dʼalliages à mémoire de forme cuivreux polycristallins. Il résume les travaux de recherche effectués par différentes équipes dont les résultats ont permis dʼidentifier les mécanismes physiques mis en jeu à différentes échelles de la microstructure.
