Properties of Dual Phase Steels

Materials Testing, 2003
Two different heat treatment (intercriticaly and intermediate heat treatments) have been applied to steels containing 0.16% C in order to obtain dual-phase steels (DPS) with different microstructures. One set of intermediate quenched samples were tempered.

Plastic anisotropy of dual-phase steels

International Journal of Plasticity, 1990
Abstract 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 ...

Failure Initiation in Dual-Phase Steel

Key Engineering Materials, 2013
This 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

Nanostructured high-carbon dual-phase steels

Scripta Materialia, 2011
A nanostructured dual-phase microstructure has been achieved by a quenching–partitioning–tempering treatment of a high-carbon super bainitic steel. Observations showed that the nanostructured steel consisted of fine martensite, retained austenite and carbides. The hardness reached up to approximately 700 HV1.

Hydrogen embrittlement of dual-phase steels

Metallurgical Transactions A, 1981
Reversible 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.

Dual-Phase Steels

2013
Abstract Dual-phase (DP) steels have the widest usage in automotive industry because of their excellent combination of strength and ductility. This chapter provides an overview of the composition, microstructure, processing, deformation mechanism, mechanical properties, formability, and special attributes of DP steels.

MACHINING CHARACTERISTICS OF DUAL-PHASE STEEL

Materials and Manufacturing Processes, 1990
ABSTRACT A dual-phase steel was produced from a hot-rolled HSLA steel ASTM-A58S by quenching from an intercritical temperature which produced a structure consisting of 80 vol.% martensite plus 20vol.%ferrite. The as-received hot-rolled structure consisted primarily of 60 vol.% ferrite plus 40 vol.% pearlite.

Work hardening of dual-phase steels

Metal Science, 1981
AbstractA 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.
