“…It is a well known fact that -due to the thermomechanical treatments -different phase transformations take place in the austenitic stainless steels and these transformation change the properties such as the mechanical ones (tensile strength, yield stress, elongation), the corrosion, and the material structure in a wide range [1]. It is a general fact, that by decreasing of deforming temperature the amount of alpha' martensite increases, the amount of austenite decreases while the epsilon martensite has a maximum curve due to γ→ε , ε→α' , γ→α' , γ→ε→α' transformations [2].…”
