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 ...

The formability of a dual phase steel
Metallurgical Transactions A, 1981The mechanical properties and the forming behavior of a dual phase sheet steel have been assessed. The effect of downgaging on forming properties was especially considered because of its importance in lighter weight, energy saving materials. A lower bound method has been used to determine the forming limit diagrams of the steel. Results have shown that

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
