The Effect of Reheating Temperature on Precipitation of a High Strength Microalloyed Steel

Abstract:

High-strength steels are usually microalloyed with niobium (Nb), titanium (Ti) and vanadium (V), individually or in combination. The reheating temperature during austenization has a significant influence on the precipitation of microalloyed steels. The purpose of the study is to investigate the effect of reheating temperature on precipitates of microalloying elements. The research results show that reheating temperature should be high enough to ensure the dissolution of carbide and nitride precipitates in order to improve the precipitation strengthening of microalloying elements during rolling and cooling. The results provide the theoretical reference for the determination of reheating technology of microalloyed steels.
