Abstract
The constrained stress-induced ε reverse martensitic transformation characteristic of Fe-Mn-Si alloy was studied by X-Ray Diffraction (XRD) and metallographic analysis. The results show that the origination temperature (As) of the constrained reverse transformation of Fe-Mn-Si alloy in cement matrix, compared with the unconstrained alloy, was immovability, the pause temperature (Af) was elevated, and the ε reverse martensitic transformation became slower under the same recovery temperature. At the same time, the amount of the constrained stress-induced ε reverse martensitic transformation decreased and the reverse transformation temperature zone broadened with the increasing degree of prestrain.
