| 内容記述 | Effects of retained austenite parameters on the deep drawability in high-strength TRIP-aided dual-phase (TDP) sheet steels with different silicon and manganese contents were investigated. The deep drawability evaluated with a limiting drawing ratio (LDR) was affected by volume fraction of the retained austenite rather than by its stability and morphology. Namely, the higher the volume fraction of the retained austenite, the larger the strength-deepdrawability balance, i.e., the product of tensile strength and LDR. The excellent deep drawability was caused by large local necking resistance at the cup wall just above the punch bottom due to "the transformation hardening" and "the stress relaxation" resulting from the strain-induced martensite transformation, as well as a low punch force of the shrinking flange. | |||||
