【 摘 要 】

Friction factor has been determined for CP aluminium and aluminium�?�zinc alloys using ring compression test at different temperatures from 303 K to 773 K. It is found that CP aluminium exhibits sticking whereas Al�?�Zn alloys do not exhibit sticking at elevated temperatures. Hot working of Al�?�Zn alloy is easier than that of CP aluminium at 773 K. As zinc content increases up to 10 wt% the friction factor decreases up to 0.02.
