摘要
研究了分级时效工艺对 1 42 0Al -Li合金组织与性能的影响 ,试验结果表明 :经 70℃ /1 2h +1 2 0℃ /4～ 1 0h工艺分级时效处理可使 1 42 0Al-Li合金的综合力学性能得到显著的提高 ;分级时效工艺使1 42 0Al-Li合金析出的δ′相粒子分布均匀。
Effect of double stage aging on microstructure and properties of 1420 Al Li alloy is studied.It is shown that the double stage aging (70℃/12 h+120℃/4 h～10 h) may greatly increase comprehensive mechanical properties of the 1420 Al Li alloys.Besides,Fine δ′ phase and uniform distribution of preciptation in Al Li alloys is obtained by the double stage aging technology.
