Abstract: In this study, a zirconium sheet was fabricated utilizing laser directed energy deposition (L-DED) technique along with its microstructure, hardness, and wear resistance to be compared with a conventionally rolled and annealed (RA) zirconium sheet. The RA specimen exhibits equiaxed grains with uniform size and a bimodal basal texture, along with a few dispersed ZrFe 2 particles. In contrast, the L-DED specimen is featured by parallel or interlaced laths (with dense entangled dislocations) and many Zr 3 Fe precipitates along the lath boundaries, exhibiting a nearly random texture. Tests reveal that the L-DED specimen shows nearly two times hardness and a ∼ 30 % reduced wear rate compared to the RA specimen. Such improvement can be jointly attributed to the enhanced second-phase, dislocation and grain refinement hardening/strengthening. This study verifies the feasibility of producing high performance zirconium materials through L-DED, which could provide some definite insight into further application of additive manufacturing to zirconium production. • Zirconium sheet was fabricated by L-DED and compared with conventionally processed sheet. • L-DED specimen is featured by lath structures with many Zr 3 Fe precipitates along lath boundaries. • L-DED specimen shows nearly doubled hardness and ∼ 30 % reduced wear rate compared to RA specimen. • Such improvement is attributed to enhanced second-phase, dislocation and grain refinement hardening.
