摘要：

A modified Crussard Jaoul analysis has been employed to describe the strain hardening behaviour (the In(dsigma/depsilon) versus In sigma curves) of a 1020 dual-phase steel with quenching and quenching + tempering treatments and with different predeformations, which demonstrated that this dual-phase steel exhibits two stages of strain-hardening in the range of plastic deformation. An analysis of instability for dual-phase steel is also presented and the relationship between the maximum uniform strain and the material parameters is proposed, which shows good agreement with the experimental results for the present 1020 dual-phase steel and other dual-phase steels.
