摘要

Laser additive manufacturing (AM) attracts great attention for its capacity of complex geometry fabrication and multiple microstructure control. This study investigates the columnar to equiaxed grain transition and its effect on the mechanical property of laser additive manufactured TiZrVNbAl lightweight high-entropy alloy (HEA). The columnar to equiaxed grain transition could occur and the equiaxed grain size could be refined to about 55 μm when the scanning line distance was increased. The fine equiaxed grain was beneficial to increase the strength and work hardening rate, which is related to the inhibition effect of the grain boundary on the dislocation slip.
