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 Mossbauer 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.eninfo:eu-repo/semantics/openAccessaustenite-martensiteMossbauer spectroscopyscanning electron microscopyisomer shiftArticle25535936010.1007/BF027080092-s2.0-0036773311Q2WOS:000178494300001Q3
