摘要	Tensile and impact tests were performed on Al-0.63 wt%Cu and Al-3.9 wt%Cu alloys subjected to equal channel angular pressing (ECAP) with different number of passes. Besides the tensile properties, data about the static toughness and the impact toughness were obtained. The strength and the toughness of the Al-Cu alloys were ameliorated and upgraded to a high level collectively. In addition, fracture surface observations show that the fracture behavior of the Al-Cu alloys changes from brittle mode to ductile mode after multi-pass ECAP.
