Abstract

The effects of the working temperature, working reduction ratio, and post-cooling rate on the microstructural change, retained austenite characteristics and shear properties of 22SiMnCrMoB transformation-induced plasticityaided martensitic steel were investigated. High shear strength, large shear elongation, and a superior combination of shear strength and shear ductility were attained by performing a rapid cooling after the warm working.
