| Abstract: | The M_5 temperature and the yield strength of austenite at M_5 tem-perature have been measured for five Fe-Mn-C alloys. The experimental results showthat there is a linear relationship between them. The effect of the solution strength-ening of austenite on martensite morphology is also studied. It is pointed outthat there is a characteristic temperature of strengthening in austenite, T_c. Marten-site morphology is mainly dislocated laths when M_5>T_c, and is mainly twinnedplates when M_5
