Effect of Intercritical Rolling on Microstructure, Mechanical and Corrosion Properties of the Dual Phase X70 American Petroleum Institute Pipeline Steel
Abstract:The effect of intercritical annealing heat treatment on mechanical and corrosion properties of fer-rite/martensite dual-phase steels with and without deformation by rolling has been investigated in this study. The X70 steel was rolled at intercritical temperatures (760 and 800 °C)
with 30% amount of reductions followed by water quenching in order to produce dual-phase microstructure. The experimental results show that microstructures, mechanical and corrosion properties and were strongly affected by intercrit… Show more
