摘要: Abstract A model using a finite element technique is used to explore the work hardening of dual-phase steel consisting ferrite and 30 vol.% martensite in true plastic strain range between 0 0.01. The basic premise that unusual produced by heterogeneous flow ferrite. This heterogeneity properties, which associated with presence an extrinsic transformation accommodation zone ferrite, describe analysis “two-phase” approximation. found be much affected extent relaxed. It shown relationship these microstructural parameters can defined good approximation single parameter, independent strain. rate experimentally measured stress-strain behavior typical are well predicted includes relaxation parameter equal 0.3.
