The Effect of Continuous Galvanizing Process Parameters on the User Properties of Hot-Rolled Transformation Induced Plasticity Steels

A hot rolled C-Mn-Si TRIP steel was subjected to three different heat treatment schedules compatible with continuous galvanizing line capabilities and the effect of the heat treatment schedules on the microstructure and mechanical properties was determined. It was found that for heat treatment schedules employing relatively high cooling rates (6 - 9°C/s) from the intercritical annealing temperature (800°C) and short overaging times at the …
