The work-hardening behaviour curve, i.e. d σ / d ε vs. ε (Fig. 3, Table 1) of TWIP steel at room temperature can be divided into four stages: (I) a sharp decrease in the work-hardening until it reached a minimum value of ~2800 MPa at a true strain of about 0.025; (II) a gradual increase in the work-hardening with the deformation up to a true …
Abstract. The plastic flow behavior of Hadfield manganese steel in uniaxial tension and compression is shown to be greatly influenced by transformation plasticity phenomena. Changes in the stress-strain (σ-ε) curves with temperature correlate with the observed extent of deformation twinning, consistent with a softening effect of twinning as a ...
