Abstract
The effect of V alloying on the creep properties of the Zn-10Al alloy at ambient temperature was investigated. V alloying significantly refined the Zn-10Al grains, and a new Al3V phase was observed. After cold deformation and heat treatment, the steady-state creep rate of the Zn-10Al-0.5 V alloy at 0.2·σ0.2 and ambient temperature was 4.65 × 10-6h−1, and decreased with increasing V content. The Zn-10Al-0.5 V alloy had a fine grain structure and maintained a favourable creep resistance owing to the dispersed Al3V, which pinned dislocations and hindered grain boundary migration.
