对铸态Al-0.63%Cu和Al-3.9%Cu(质量分数)合金进行等通道转角挤压处理, 研究了Al-Cu合金冲击性能的变化. 结果表明, 等通道转角挤压增强了Al-0.63%Cu合金的冲击性能; 而对于Al-3.9%Cu合金, 虽然晶粒细化和第二相的弥散分布使其强度增加, 但较多的第二相θ (Al2Cu)未提高其冲击性能. 该合金的冲击吸收功与其静力韧度有关.
Impact properties of casting Al-0.63wt.%Cu and Al-3.9wt.%Cu alloys subjected to equal channel angular pressing (ECAP) were investigated. It is found that the impact properties of Al-0.63wt.%Cu alloy were enhanced after ECAP. While for Al-3.9wt.%Cu alloy, its impact toughness was not improved, although the tensile strength increased as a result of grain refinement and second-phase dispersion. It is shown that the impact toughness is dependent on the static toughness of the Al-Cu alloys.
