摘要：
In this work, coarse-grained 316 L stainless steels were cold rolled with a thickness reduction of ～83%(CR 83%).After annealing, the behaviors of the nanostructured stainless steel samples were systematically investigated in the temperatures range of 200C–650C. It was found that with increasing annealing temperature the volume fraction of the α0-martensite first increased to reach a maximum value at 400C, then the volume fraction decreased with further increases of the annealing temperature. The yield strength was increased from 1400 MPa to 1720 MPa after annealing; this strong hardening effect in cold rolled 316 L stainless steel was mainly attributed to the increase of the volume fraction of α0-martensite.
