Abstract

Out-of-phase cyclic tension and torsion tests followed by metallographic measurements are carried out on Co33Ni specimens. It appears that, even for small strain ranges, nonproportional loadings induce profuse mechanical twinning and a strong kinematic hardening in this low stacking-fault-energy f.c.c. alloy. These results are analysed and an attempt to incorporate twinning into micromechanical simulations of f.c.c. polycrystals elastoplastic behaviour is described.
