Effect of Ti/N Ratio on Impact Strength of High Strength Pipe Steel Welded Joint Heat-Affected Zone

Effect of Ti/N Ratio on Impact Strength of High Strength Pipe Steel Welded Joint Heat-Affected Zone

Kinetics of austenite grain growth within a heat-affected zone is studied for low carbon low-alloy steels of different alloying composition. The effect of Ti/N ratio on the metal impact strength of the heat-affected zone is demonstrated.
