The experimental results reveal that two types of thermal-induced martensites, epsilon (hcp) and alpha' (bcc) martensites, are formed in the as-quenched condition, and these transformations have athermal characters. Mo addition to the Fe-Mn alloy does not change the coexistence of epsilon and alpha' martensites with the Mn content between 10wt% and 15wt%. Besides, Mossbauer spectra reveal a paramagnetic character with a singlet for the gamma (fcc) austenite and epsilon martensite phases and a ferromagnetic character with a broad sextet for the alpha' martensite phase. The volume fraction of alpha' martensite forming in the quenched alloy is much more than that of the epsilon martensite.eninfo:eu-repo/semantics/closedAccessFe-Mn alloymolybdenummartensitic transformationscanning electron microscopy (SEM)transmission electron microscopy (TEM)Mossbauer spectroscopyArticle17444845210.1007/s12613-010-0339-z2-s2.0-77955615279Q1WOS:000280776300010Q3
