Effect of Corbon Content on the Structure and Mechanical Properties of TI-10V-2Fe-3Al Alloy

Abstract

The effect of carbon content on microstructure and mechanical properties of the transition (α+β)-titanium alloy Ti–10V–2Fe–3Al in a heat-strengthened state was studied. It was established that with the increase of carbon content in the alloy up to the limit of its solubility in a solid solution, the strength of the alloy increases, the plastic characteristics decrease. When the solubility limit of carbon in a solid solution in an alloy is exceeded, the appearance of titanium-based carbide particles was observed, while the strength of the alloy somewhat decreases, due to the decrease of the effect of solid-solution hardening from the elements present in the alloy, which are partially transferred from the solid solution to the titanium-based carbide particles.
