Heat treatments and thermomechanical cycling influences on the R-phase in Ti-Ni shape memory alloys

This article studies changes observed on the R-phase thermoelastic behavior in a near-equiatomic Ti-Ni shape memory alloy. Three kinds of procedures have been performed: different treatments, thermomechanical cycling under constant loading in shape memory helical springs and thermal cycling in as-tr...
