N2 - Low-cycle fatigue (LCF) properties of the Fe-30Mn-(6-x)Si-xAl alloys ascribed to TRIP/TWIP high-Mn austenitic alloys were examined in relation with tensile properties. It was found that fatigue resistance of these alloys correlates with tensile yield strength and strain hardening rate, while tensile ductility are not affects LCF properties of examined alloys. At total fatigue strain range of 2% the highest fatigue life of about 8000 cycles was found in the Fe-30Mn-4Si-2Al alloy with higher yield strength (YS) and lower hardening rate. Decreasing of YS and increasing of hardening rate lead to considerable decrease of fatigue life of examined alloys. In the presentation we will discuss the relation between LCF properties and deformation microstructure.
