Columnar to equiaxed transition during β heat treatment in a near β alloy by laser additive manufacture

Columnar β grains are widely present in titanium alloys fabricated by Additive Manufacturing (AM), which leads to significant anisotropy in mechanical properties. An outstanding challenge is to facilitate the columnar to equiaxed transition (CET) of the prior β grains. In this research, CET and the...
