A new (α + β) Ti-alloy, Ti-6Al-2V-1Cr-1Fe (wt%), with fine grain sizes, fine precipitates, together with the high strength and excellent ductility in its as-cast state is developed. As compared to the as-cast commercial Ti-6Al-4V alloy, the grain size and α lath thickness of the new alloy are substa...
