| Abstract: | The work softening behaviors and mechanisms of three kinds of pure aluminium and three Al 2? alloys in the rolling state at room temperature were studied. the results show that when the rolling ratio is over 80%, there occurs work softening in the 99.996%Al but not in the 99.96%Al and 99.6%Al; that there occur work softening in the Al(99.996%)-2? alloy when the rolling ratio is over 60% and in the Al(99.96%)-2? alloy when the rolling ration is over 90%, but not in the Al(99.6%)-2? alloy. The main reason of work softening is room temperature recovery which is caused by the dispersive second phases. |
