【 摘 要 】

properties and structural stability. In a series of studies, Zn - (25-26) wt.% Al - (1-2.5) wt.% Cu alloys have been doped with different levels of added Ti. The alloys’ structure and mechanical properties have been studied using: SEM (scanning electron microscopy), LM (light microscopy), Dilatometry, Pin-on-Disc wear and Strength measurements. Grain refinement leads to significant improvement of ductility in the binary Zn-25Al alloy. In the ternary alloys Zn-26Al-Cu, replacing a part of Cu with Ti allows dimensional changes to be reduced while preserving good tribological properties.
