摘要	An 18Cr-8Ni austenitic stainless steel is subjected to cold rolling at room temperature and low temperature (-50 degrees C) under different amounts of deformation. The samples cold rolled to 70% deformation are then annealed to obtain nano/ultrafine-grained steels with a good strength-ductility combination. The effects of cold rolling temperature and deformation amount on the microstructure evolution of austenitic stainless steel during rolling are investigated. The results reveal that low-temperature rolling reduces the stacking fault energy of austenitic stainless steel and promotes the formation of shear bands, epsilon-martensite, and alpha '-martensite. For both low-temperature and room-temperature rolling, the austenite and alpha '-martensite, austenite and epsilon-martensite, alpha '-martensite and epsilon-martensite pairs follow the Kurdjumov-Sachs (K-S), Shoji-Nishiyama (S-N), and Burgers orientation relationships, respectively. The deformation-induced martensite transformation sequence of austenitic stainless steel follows the processes gamma -> alpha' and gamma -> epsilon -> alpha'. A heterogeneous nano/ultrafine-grained structure with a grain size of 560 nm is obtained by low-temperature rolling and annealing; room-temperature rolling achieves a grain size of 690 nm. The heterogeneous nano/ultrafine-grained steel exhibits a high yield strength of 908 MPa and maintains a satisfactory total elongation of 43%.
