Effects of carbon addition on microstructure of Ti-V alloys formed at high temperatures were investigated.    By adding carbon to pure Ti and Ti-V binary alloys, precipitation of TiC occurs. With increase of vanadium content, β/(β+TiC) phase boundary shifts to the lower carbon side slightly. On the other hand (α+β)/(α+β+TiC) boundaries shifts largely with decreases in α fraction and peritectoid reaction temperature by addition of vanadium.    Addition of carbon to a Ti-15V-3Cr-3Sn-3Al alloy results in extensive suppression of recovery during hot deformation of β phase by carbon in solution. Also age hardening kinetics of Ti-15V-3Cr-3Sn-3Al after β solutionizing was accelerated by carbon addition.
