Friction factor of CP aluminium and aluminium�?�zinc alloys

[摘要] Friction factor has been determined for CP aluminium and aluminiumâ€�?�zinc alloys using ring compression test at different temperatures from 303 K to 773 K. It is found that CP aluminium exhibits sticking whereas Alâ€�?�Zn alloys do not exhibit sticking at elevated temperatures. Hot working of Alâ€�?�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.
