Effect of Niobium Addition on the Mechanical Properties of Ti Stabilized Interstitial-Free Steel

Abstract:

Article Preview

Two interstitial-free steel grades, one based on combined niobium and titanium additions and the other based on titanium only addition, were investigated. Annealing experiments were used to study the effect of niobium on the mechanical property. And tensile-shear fatigue tests were used to study the effect of niobium on the fatigue property of spot welding. The experimental results show that niobium addition not only can significantly improve the mechanical properties of the basic materials by way of grain refinement, but also has beneficial effects to the fatigue strength of spot welding.
