The present research studies the effect of bismuth addition on castability, structure and mechanical properties of Ti-6Al-4V alloy. Experimental results indicate that addition of 1 wt.% bismuth in Ti-6Al-4V enhances both castability and strength of the alloy. Larger amounts of Bi addition caused a reduction in ductility. Undoped and 1Bi-doped alloys exhibited a ductile fracture surface covered with deformation dimples, while 3Bi and 5Bi alloys showed a brittle fracture surface.
