- (1)
- The alloys after Zr addition were composed of a single BCC phase. Upon increasing the Zr content, the lattice constant and solid solution strengthening increased. The alloy structure transformed from an equiaxed crystal-dendritic to a crystal-equiaxed crystal morphology, and the alloy grain size first decreased and then increased.
- (2)
- A proper amount of Zr alloying increased the strength and hardness of the alloy while maintaining its plasticity. Compared with the Zr0 alloy, the yield strength and compressive strength of the Zr0.5 alloy were increased by 18.47% (to 1314 ± 33 MPa) and 18.14% (to 1673 ± 11 MPa), respectively. Additionally, Zr0.5 exhibited the maximum hardness (516 ± 52 HV).
- (3)
- Zr0.5 alloy had the widest wear scar, a relatively low depth, the greatest degree of wear on the grinding ball, and the best wear resistance. These properties were attributed to the generation of an oxide film on the wear surface, which acted as a lubricant.
