to the super-high aluminum alloy. 2 Experimental The cast ingots... Retrogression and re-aging treatment of Al-9.99%Zn-1.72%Cu-2.5%Mg-0.13%Zr aluminum alloy FENG Chun(冯 春)1, LIU Zhi-yi(刘志义)1, NING Ai-lin(宁爱林)1,2, LIU Yan-bin(刘延斌)1, ZENG Su-min(曾苏民)1 1. School......
the strength and wear resistance of aluminum alloy parts in automotives. Long duration time as well as long pre-sputtering time are required for plasma nitriding of aluminum or its alloys only with the thickness of a few micrometers. New plasma inner nitriding is proposed to realize the fast-rate nitriding of aluminum alloys. Al-6Cu alloy is employed as a targeting material in order to demonstrate......
