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, 1990ABSTRACT 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, 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.

Abstract Dual-phase steels are a new class of high-strength low alloy (HSLA) steels characterized by a microstructure consisting of about 20% hard martensite particles dispersed in a soft ductile ferrite matrix. In addition to high tensile strength, in the range of 550 MPa (80 ksi), dual-phase steels exhibit continuous yielding behavior,

Nanostructured martensite–austenite dual phase steels
Materials Science and Technology, 2012Nanostructured martensite–austenite microstructure was achieved by a quenching–partitioning–tempering (Q–P–T) treatment of high carbon low temperature bainitic steel. Microstructure observations showed that the nanostructured steel consisted of fine martensite (about 25 nm in thickness), retained austenite and carbides.

The formability of dual-phase steels
Journal of Applied Metalworking, 1982The formability of both heat-treated and as-hot-rolled dual-phase steels was evaluated in neck- and fracture-limited forming modes and compared with the formability of conventional high-strength low-alloy (HSLA) or microalloyed steels. For both production routes the formability of dual-phase steels was found to be sensitive to tensile strength ...

Fatigue of a dual- phase steel
Metallurgical Transactions A, 1979A study has been made of the fatigue of a V containing dual-phase steel, whose tensile strength is equivalent to that of SAE 980X high strength, low-alloy (HSLA) steels, as a function of prestrain. It is found that the cyclic stress-strain curve, strain-life response and notch sensitivity are little affected by pre-strains of up to 8 pct: This is in ...
