The thermal stability of the reversed austenite in a low carbon Fe-13%Cr-4%Ni-Mo (in wt pct) martensitic stainless steel was investigated by X-ray diffraction (XRD) and superconducting quantum interference device (SQUID) magnetometer. Different amount of the reversed austenite was obtained by controlling tempered temperature. It was found that the amount of the reversed austenite increased after keeping the specimens at liquid nitrogen temperature for 72 h. The mechanism of the anomalous phase transformation from martensite to austenite was discussed.
