    • Abstract

       

      In this study, austenite–martensite phase transformations which are formed by cooling effect in Fe–30% Ni–0.2% Mn alloy are investigated with Mössbauer spectroscopy and scanning electron microscopy. The single peak of the paramagnetic phase and the six peaks of the ferromagnetic phase of Fe–30% Ni–0.2% Mn alloy were observed in the Mössbauer spectrum. The internal magnetic field strength of ferromagnetic martensite phase was determined as 33.8 𝑇 and the isomer shift values were determined as – 0.11 mm.sec–1 and – 0.06 mm.sec–1, respectively, for the austenite and martensite phases. In this alloy, athermal transformation was observed. The results obtained are in agreement with literature.
