Micromechanical modelling for tension-compression pseudoelastic behavior of AuCd single crystals

On one hand, the experimental crystallographic data of Chang and Read and t he theoretical ones of Lieberman et al. permit a physical approach of the m artensitic transformation of Au-47.5% at. Cd. On the other hand, an extensi on to the AuCd crystallographic system of the simple micromechanical model, developed by Lexcellent et al. for CuZnAl single crystals, allows an effic ient modelling of the tension-compression and pure tension tests, performed on single crystals by Nakanishi et al. in the pseudoelastic range.
