| 摘 要： | In order to develop a new high strength and high tolerance-resistance Al-Li alloy which can be used in aerospace industry, the effects ofmicroalloying elements such as Mg, Ag, Mn and Zn on the mechanical properties of Al-Cu-Li alloys were studied. The results show that the strengthening effects of Mg＋Ag and Mg＋Zn additions are higher than those of the individual Mg, Ag or Zn addition. The element Mn can also bring some extent strengthening effects on the alloys, but it has nothing to do with the other microalloying elements present or not. Finally, a new Al-Li alloy with Mg＋Zn＋Mn additions was developed, which possesses high strength and high tolerance-resistance promising properties for aerospace applications.
