| Abstract: | The precipitation features of different phase fields in Al-Cu-Mg alloys were introduced. The effect of trace Ag on microstructure and mechanical properties of Al-Cu-Mg alloys were summarized. Addition of trace Ag is known to modify precipitation processes in Al-Cu-Mg alloys with different Cu/Mg ratios, to promote the formation of new phase that has better thermal stability, so that their response to strength and heat-resistant properties is enhanced. |
