摘要	The regulation of structure and composition is very important for obtaining stainless steel with good comprehensive properties. Fe2O3 powers with different excess fraction were added in reaction powders to make complete aluminothermic reaction and reduce the content of Al in 316L ASSs. The effects of excess Fe2O3 in reactions on microstructure and tensile properties of micro-nano structure of 316L austenitic stainless steels were analyzed. The results show that with the increase of Fe2O3 excess fraction, the volume fraction of ferrite phase reduces significantly while the volume fraction of nanocrystalline increases from 87.4% to 93.4% and the average grain size decreases from 32 nm to 22 nm. The comparative analysis shows that the Fe2O3 excess fraction of 5.0 % is the best processing parameter for the 316L ASSs preparation by the aluminothermic method. For the single phase austenitic steel prepared under this condition, the tensile strength is 573.92 MPa, the yield strength is 340.12 MPa, and the elongation is 4.68%.
