Abstract
A metastable austenitic stainless steel was repetitively cold rolled and reversely annealed. The strain-hardening behavior and deformation mechanism during tensile testing were comparatively studied for the specimens annealed at 800 °C and 1000 °C. Fine-grained austenite with uniformly distributed carbides was formed in the 800 °C-annealed specimen, whereas coarse-grained austenite without carbides was obtained with annealing at 1000 °C. Continuous strain hardening was achieved in all specimens, which could be attributed to the strain-induced martensite and deformation twining for the annealed specimens at 800 and 1000 °C, respectively. The carbide precipitation promoted the formation of strain-induced martensite due to the depletion of austenite stabilizers.
