【Abstract】 Effect of technological parameter of Thermomechanical Control Process on microstucture and mechanical properties of Nb-Ti microalloyed automotive steel were investigated. The relationship between technological parameter and mechanical properties were analyzed. A lot of the production speciment have been taken for mechanical property test. On a THERMECMASTOR-Z hot simulator experiment, the effect of deformation、finish cooling temperature and cooling rate on the yield strength and tensile strength has been studied in this paper. The obtained data can be used for reference to get the required mechanical properties in production.更多还原
