Aluminum-lithium-copper alloys have a low density, high elastic modulus and high specific strength. Due to this combination of properties, alloys strengthened with the ternary (Al-Li-Cu) T1 phase have attracted a great deal of interest especially in aerospace applications. Determining the atomic str...
