Four Al-Cu-Li alloys were casted.Their chemical compositions are shown in Table 1.Alloy 1#and alloy 2#were used to investigate the effect of independent In addition on Al-Cu-Li alloy.Their Cu and Li concentrations were controlled to be3.4%and 1.0%as far as possible.Because of uncontrollable factors during melting,there are small differences,but it was still valid.Alloy 4#is a nominal 2050 Al-Li alloy,and alloy 3#and alloy 4#were used to investigate the different micro-alloying effects of Ag+Mg and In+Mg combined additions.
