The kinetic,morphological,crystallographic,and magnetic characteristics of thermally induced martensites in Fe-13.4wt%Mn-5.2wt% Mo alloy were investigated by scanning electron microscopy(SEM),transmission electron microscopy(TEM),and M(o)ssbauer spectroscopy.The experimental results reveal that two types of thermal-induced martensites,ε(hcp)and αˊ(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 ε and αˊ martensites with the Mn content between 10wt% and 15wt%.Besides,M(o)ssbauer spectra reveal a paramagnetic character with a singlet for the γ(fcc)austenite and ε martensite phases and a ferromagnetic character with a broad sextet for the αˊ martensite phase.The volume fraction of αˊmartensite forming in the quenched alloy is much more than that of the ε martensite.
