Abstract TWIP-cored three-layer steel sheets were newly fabricated by hot rolling of TWIP sheet surrounded low-carbon (LC) or interstitial-free (IF) sheets. TWIP/LC TWIP/IF interfaces well bonded without pores voids, while a few pearlites thinly formed along the interfaces. The strengths and elongation increased as volume fraction region increased, also matched with ones calculated rule mixtures based on force fraction. According to digital image correlation electron back-scatter diffraction...
Phenomena occurring in duplex lightweight steels under dynamic loading are hardly investigated, although its understanding is essentially needed applications of automotive steels. In this study, quasi-static and tensile properties were investigated by focusing on how TRIP TWIP mechanisms varied the conditions. As annealing temperature increased, grain size volume fraction austenite thereby gradually decreasing stability. The strain-hardening rate curves displayed a multiple-stage behavior,...
