Pd-In-Fe shape memory alloy

摘要

Martensitic, magnetic transformations, and crystal structures in Pd-In-Fe alloys were investigated. It was confirmed that some Pd-In-Fe alloys show martensitic transformation from a Heusler-type (L2_1) ordered bcc phase to a 2M-type (DO_(22)) structure and that an almost perfect superelastic effect accompany the transformation can be obtained. Furthermore, some alloys show transformation from the paramagnetic parent phase to the ferromagnetic martensite phase.
