The Al-Li alloy powder was prepared by argon atomization.It was canned in an aluminum containerand then the compact powder billet and I/M Al-Li ingot were extruded into Φ17 mm at 450°C with anarea reduction of 34:1.Compared the tensile properties between RS-P/M and I/M A1-Li alloys,also stu-died their process,microstructure and the mechanism of the ageing strengthening in the alloy. 相似文献
