In this review, effects of initial microstructure before intercritical annealing and processing
routes of dual phase (DP) high strength steels are discussed. Prior-applied deformation …

The formulation of the so-called homogeneous anisotropic hardening (HAH) model, which
was originally proposed in Barlat et al.(2011), is refined. With the new features, this …

Both increased weight reduction and improved passive safety have been simultaneously
required for components of new vehicle generation. Thus, advanced high strength Dual …

Dual phase (DP) steels were produced by a new approach utilizing simple cold-rolling and
subsequent intercritical annealing of a ferrite–martensite duplex starting structure. The …

To reduce cost, optimise mechanical properties and improve process tolerance, a series of
1000MPa grade ultrafine-grained dual phase (DP) steels with nanosized precipitates have …

This paper aims to identify the mechanisms associated to the transient hardening behaviour
of dual phase steels under strain path changes, and to capture the observed material …

The stress–strain response of some materials, such as advanced high strength steels,
during unloading is nonlinear after the material has been loaded into the plastic deformation …

With the widely use of high-strength steel sheets in the automotive industry, the twist
springback phenomenon of the steel sheets under multi-step forming conditions has …

Twist springback induced by unbalance elastic deformation and residual stresses in a sheet
after a forming is of particular importance and complexity. The twist springback can be …

Although time-dependent springback is minor compared with instantaneous springback, its
deformation-history dependent effects may deteriorates the compactness of parts assembly …
