Plastic anisotropy of dual-phase steels
International Journal of Plasticity, 1990Abstract A continuum mechanics model on yielding and plastic deformation of dual-phase steels consisting of a large number of spherical second-phase islands dispersed in a matrix has been developed. The model is based on the Hill's theory on orthogonal anisotropy and the mean internal stress arising from the differences in strengths and plastic ...

Hydrogen embrittlement of dual-phase steels
Metallurgical Transactions A, 1981Reversible hydrogen embrittlement (HE) is usually only found in quenched and tempered steels with yield stresses in excess of 1035 MPa (150 ksi). A study of the HE phenomena in two dual-phase steels with tensile strengths of about 690 MPa (100 ksi) has shown that these steels are susceptible to the presence of hydrogen.

Role of vanadium in dual-phase steels
Metals Technology, 1981The effects of varying the annealing temperature and cooling rate on the strength, ductility, and microstructure of a plain carbonsteel, and a similar steel containing 0·06%V, are reported.

Work hardening of dual-phase steels
Metal Science, 1981AbstractA detailed qualitative and quantitative microstructural examination of four dual-phase steels has been carried out. Dual-phase structures were produced in three of these steels by intercritical annealing; the other was in the as-rolled condition. Similar combinations of tensile properties were obtained with all four steels.

Failure Initiation in Dual-Phase Steel
Key Engineering Materials, 2013This research work aims to model the failure initiation in dual-phase (DP) steel. A microstructure based approach by means of representative volume elements (RVE) is employed to evaluate the microstructure deformation and the failure initiation on the mesoscale. In order to determine cohesive parameters for martensite cracking, a two level approach has

Dual-phase and other formable steels
Metals Technology, 1983AbstractWhile high-strength low-alloy steels have been available for some considerable time, and have found extensive application, their use in certain areas has been restricted by other property requirements, such as formability. Developments in improved stretch-forming steels are reviewed.
