摘要

Precipitation-hardenable, nitrided aluminum alloys are produced by forming an alloy of aluminum metal at a temperature up to about 800. degree. C with a nitrided mother alloy of a specified composition which has been nitrided at a temperature of 800° to 1, 200° C. The aluminum alloys are made precipitation-hardenable by the incorporation therein of a precipitation-hardening component such as copper, zinc and/or magnesium, and the precipitation-hardening component can be contained in the mother alloy undergoing nitridation.
