The constrained stress-induced ε reverse martensitic transformation characteristic of Fe-17Mn-5Si-10Cr-5Ni shape memory alloy wire embedded in cement matrix was studied by X-Ray Diffraction (XRD) and metallographical. The results show that the finish temperature (Af) of the constrained reverse transformation of Fe-17Mn-5Si-10Cr-5Ni shape memory alloy in cement matrix, compared with the unconstrained alloy, is elevated. With increasing the pre-strain, the Af is higher, and reverse transformation temperature zone is broadened. The main result which causes martensitic reverse transformation harder is that Fe-Mn-Si alloy deformation coordination is limited by cement matrix constrained.

The use of smart material such as Ti-Ni in actuators application requires an intense mechanical and metallurgical investigation to understand its behavior. This paper studies martensitic transformation using DSC and X-ray diffraction techniques to compare shape memory parameters in Ti-50.2%Ni (A1) and equiatomic Ti-50.0%Ni (A2) Alloys. The as as-received samples were submitted to annealing at 400°C and 500°C for 24 hours then quenched in at 25°C. The influence of heat treatment on martensitic transformations temperatures and the appearance of R-phase were analyzed using DSC and X-ray diffraction.
