Abstract

Abstract

In this paper the ability of Nb-V, Nb-Ti and Nb-V-Ti microalloyed steels to resist growth of austenite grains and the influence of N on the ability of Nb-V-Ti microalloyed steel to resist growth of auxtenite grains are studied. Test results indicate that microamount Ti addition can greatly enhance the ability of Nb-V-Ti microalloyed steel to resist growth of austenite grains,with the increase of N content the ability of Nb-v-Ti steel to resist growth of austenite grains increases,but too much content of N decreases toughness of welding heat affected zone.
