Hot Ductility Behavior of V-N Microalloyed Steels

Abstract

The hot ductility of commercially cast 0.07 wt.% C steels containing 0.04 and 0.09 wt.% V was investigated using two experimental methods. This included utilizing a load frame equipped with resistance heating and a thermomechanical simulator. In the low-vanadium steel, the ductility loss was observed from 700-850℃, below Ar3 temperature. In comparison, ductility loss for the 0.09 wt.% V alloy occurred above the Ar3 temperature. Both methods showed similarity in the position of the low-ductility trough. The depth of the trough was related to heating/cooling rate during the tensile test. Factors influencing steel ductility are discussed.
