| Abstract: | Based on 319.0 alloy,the content of Cu and Mg was first adjusted,then other trace elements were added,and finally the new-type Al-Si-Cu-Mg aluminum alloy was formed.Compared with traditional aluminum alloys,the new alloy had better ambient and high temperature performance and its mechanical performance outwent that of traditional alloy.Using usual methods,the casting properties of Al-Si-Cu-Mg alloy were tested.Through the trial-production,it was proved that Al-Si-Cu-Mg alloy could meet the molding requirement of cylinder head.By the phase diagram analysis and microstructure observation,the strengthening mechanism of Al-Si-Cu-Mg alloy was understood and the conclusion that the aging strengthening of Mg was better than that of Cu was drawn. |
