INVESTIGATION ON WORK SOFTENING BEHAVIOR OF ALUMINUM AND ITS ALLOYS WITH IRON

Work softening in aluminum and its alloys (Al-2Fe) was investigated at room temperature, Work softening was noticed in aluminum with a purit y of 99.996 %, in an Al-2Fe alloy with a purity of 99.996 % in the alu minum matrix, and in an Al-2Fe alloy with a purity of 99.96% in the al uminum matrix, when the reduction in thickness of samples after rollin g is more than 80%, 60%, and 90%, respectively, Work softening was mai nly related to the recovery at room temperature, The addition of iron to aluminum purifies the aluminum matrix, The dispersed second phases formed by aluminum and iron may promote the recovery.
