Role of vanadium in dual-phase steels

Metals Technology, 1981
The 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, 1984
La 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

2012
En 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, 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 ...
