摘要
Equal-channel angular pressing (ECAP) was demonstrated to be an effective tool for achieving a substantial reduction in the grain size of a commercial aluminium alloy. The reduction in grain size gave an increase in the microhardness of the alloy and an increase in the proof stress by a factor of three times. The measured elongations to failure were reduced from 35% at room temperature in the unpressed alloy after ECAP.
