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.
