Abstract：In order to study the effect of cyclic loading on the microstructure and mechanical properties of austenitic steel,the fatigue properties of manganese steel in reverse phase transformation were studied. The microstructure was characterized by SEM,EBSD,XRD,etc.,and uniaxial tensile test was used to characterized the mechanical properties before and after fatigue. The research results show that under the test condition of stress ratio R=-1,the median fatigue limit of reverse phase transformation manganese steel is 378 MPa,and the ratio of fatigue limit to tensile strength σ-1/Rm=0.48. Medium manganese steel is ultrafine grain size characteristics are conducive to hindering secondary fatigue crack growth,and the transformation behavior of metastable austenite is greatly affected by the stress amplitude. Under the stress level of the median fatigue limit,metastable austenite and uniaxial tensile properties are subject to cyclic loading has little effect.
