Spot Weldability of Dual-Phase Steel
SAE Technical Paper Series, 1979<div class="htmlview paragraph">The spot welding characteristics of VAN-QN (80), a dual-phase HSLA steel, were examined with regard to the strength and ductility of spot welds under static, impact and cyclic loading and compared to a conventional V-N HSLA steel and SAE 1008 low carbon steel.</div> <div class="htmlview paragraph">The ...

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

Abstract Dual-phase (DP) steel is comprised of ferrite and martensite obtained from low-carbon or low-alloy high-strength steel through specific heat treatment processes, such as critical zone heat treatment or controlled rolling and cooling.

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.

On initial yielding in dual-phase steel
Scripta Metallurgica, 1984La presence de contraintes residuelles devrait diminuer la limite d'elasticite mais, en fait, ce dont temoignent les resultats experimentaux, elle l'accroit, et ce, on ne peut mieux, quand la fraction de martensite ...

Friction drilling of dual phase steels
2012En este trabajo se expone un estudio del proceso de taladrado por fricción en chapas de diferentes aceros de doble fase (DP), con límites elásticos variables desde 600 hasta 800 MPa. Se realiza una evaluación de las condiciones óptimas de mecanizado en función del material y el espesor empleado, variando las velocidades de giro y los avances de ...

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 ...
