From: Tensile property improvement of TWIP-cored three-layer steel sheets fabricated by hot-roll-bonding with low-carbon steel or interstitial-free steel

Figure 7

Enlarged stress-strain curves of the strain rate jump test of the TWIP, LC, and T6L sheets in the (a) initial and (b) later stages of tensile deformation, and (c) the variation of SRS as a function of strain. The strain rate sensitivity (SRS) value of the TWIP sheet relatively abruptly decreases with increasing strain, and becomes negative at the strain of 17%. In the LC and T6L sheets, all the SRS values are positive, although they are slowly decreased with increasing strain.
