Abstract

An Fe-33Ni-12Co-5Ti (wt.%) alloy was subjected to aging treatments to determine the effect of ausaging (at 700 °C for 5, 10 and 30 hr) on the martensitic transformation and shape memory effect. The Ms temperatures were determined by electrical resistance measurements and microstructures were examined by TEM. The shape memory was studied by bending specimens in liquid nitrogen and found to be associated with a low Ms thermoelastic thin plate martensite.
