摘要

The effect of deformation temperature on the mechanical properties of 1-GPa-grade TRIP steels with different retained austenite (γr) morphologies was studied. The temperature dependence on the deformation-induced martensitic transformation behavior was also investigated. The uniform elongation below room temperature was relatively large in the needle-like γr steel, whereas the tensile strength at each temperature was almost the same as it was independent of the γr morphology. The better tensile strength-uniform elongation balance was obtained at 373 K for the needle-like γr steel and at 473 K for blocky γr one. The mechanical stability of γr was higher in the needle-like γr steel, according to the x-ray diffraction experiments, γr was mechanically stable with increasing temperature, but its volume fraction decreased at temperatures above 473 K because of the deformation-induced bainitic transformation. In this paper, the quantitative conditions of deformation-induced transformation to obtain better uniform elongation in the 1-GPa-grade TRIP steels are summarized from the viewpoints of the volume fraction of deformation-induced martensite and the transformation rate.
