摘要: Abstracts In this work, the qualCONVERSION(0ities of sheet formability (i.e., stretchability and drawability), twinning-induced plasticity (TWIP), steel-cored thr$ee-layer steel sheets were investigated in terms tensile parameters strain hardening exponent, rate sensitivity, normal anisotropy, mean R -value, total elongation). The TWIP three-layer follow force-based rule mixtures. limit drawing ratio, measure drawability, was proportional to -value sensitivity while dome height (LDH), stretchability, could not be correlated with any parameters. LDH layer superior that single due inhibition serration steel-core during Erichsen test.
