Abstract
In Fe-Mn-Si and Fe-Mn-Cr steels, γ and ε phases, which give rise to shape memory effect, were observed at room temperature. In order to determine the transition temperatures, different methods were carried out. Depending on the method, the results were different. The transition temperatures either appeared or were not found in the studied temperature range. It was thought of developing a stress induced martensite to improved the results, particularly those obtained by X ray diffraction experiments.
