Abstract :
In this study the effect of Al–5Ti–1B grain refiner on the structural characteristics and wear properties of
Al–12Zn–3Mg–2.5Cu alloy was investigated. The optimum amount for Ti containing grain refiners was selected as 2
wt.%. T6 heat treatment, (i.e. heating at 460 °C for 1 h before water quenching to room temperature and then aging
at 120 °C for 24 h) was applied for all specimens before wear testing.
Dry sliding wear resistant of the alloy was performed under normal atmospheric conditions. The experimental results
showed that the T6 heat treatment considerably improved the resistance of Al–12Zn–3Mg–2.5Cu alloy to dry sliding
wear.
