摘要：

In this study, the effect of Zn additions on the mechanical properties of Al-Si-Mg-Cu alloys was investigated. From the results, it has been found that the formation of Mg-Zn intermetallic compounds is considered to be the main reason for the sharp changes in the mechanical properties of this alloy system. The microstructure showed that Mg-Zn intermetallic compounds were formed between the reinforcement phase like Mg2Si phase and the matrix became more brittle as the amount of Zn addition was increased. Upon these results, we could confirm that the formation of Mg-Zn intermetallic compounds and brittle matrix are the main reasons for the remarkable changes in the mechanical properties of this alloy system.
