Abstract: The crack propagation of 0.1C-5Mn medium manganese steel with ferrite and metastable austenite as matrix and QP980 steel with ferrite, martensite and metastable austenite as matrix were tested by load control. The crack propagation behavior was characterized by SEM and EBSD. The results show that the crack propagation mechanism is composed of sliding and accumulation damage. In the plastic zone of the crack tip, TRIP effect occurred in both the cold-rolled medium manganese steel and QP980, which transfer into martensite. The content and stability of the metastable austenite in the cold rolled medium manganese steel are higher than that in QP980, and almost all the austenite at the crack tip of QP980 transformed. The fatigue crack propagation rate is reduced by the energy absorbed by phase transition and the crack closure effect.
