Ti6Al4V alloy, produced by investment casting using yttria stabilized zirconia, was machined and then mill-annealed in vacuum furnace. The ultimate strength, yield strength and percentage elongation were largely improved compared to the same alloy in the as cast condition. The mill annealing temperature and time strongly affected the ultimate strength, 0.2% yield strength and the percentage elongation.
