A study on obtaining equiaxed prior-p grains of wire and arc additive manufactured Ti-6Al-4V

A Ti-6Al-4V alloy wall with 80 vol.% equiaxed prior-beta grains was fabricated via wire and arc additive manufacturing. However, the equiaxed prior-beta grains were characterized by strong texture. Formation mechanisms of the equiaxed prior-beta grains were discussed. The tensile results presented a much lower anisotropy than that in other studies.
