Highlights As-deposited sample exhibits columnar morphology and strong tensile anisotropy. The α+β annealing do not change the grain morphology and the anisotropy. The columnar grains transform into equiaxed grains during β annealing. The β annealing substantially decreases the tensile anisotropy.
Abstract The anisotropy of laser melting deposition additive manufacturing Ti–6.5Al–3.5Mo–1.5Zr–0.3Si was studied by microstructure observation and room tensile properties testing. The as-deposited sample exhibits a strong tensile anisotropy due to the columnar grains morphology and the strong texture of β 〈001〉 parallel to the deposition direction. Annealing in the upper α+β region has little effect on the grain morphology and the anisotropy. However, annealing in the single β region transforms the grain morphology from columnar to equiaxed which substantially reduces the tensile anisotropy to a very low level.
