Abstract：

JMatPro　software　was　used　to　optimize　the　composition　of　Al-13Si　alloy,　and　the　composition　of　Al-13Si-3.5Cu-1.3Mg-3Ni　alloy　was　obtained.　The　equilibrium　phase　diagram　of　the　Al-13Si-3.5Cu-1.3Mg-3Ni　alloy　was　obtained　by　using　Pandat　phase　diagram　calculation　software.　The　effects　of　different　heat　treatment　processes　on　the　microstructure　and　properties　of　hypereutectic　Al-Si　alloy　were　studied　by　OM,　SEM,　EDS　and　XRD.　The　results　showed　that　the　optimal　heat　treatment　process　of　the　Al-13Si-3.5Cu-1.3Mg-3Ni　alloy　was　solution　at　500　℃　+4　h　and　aging　at　185　℃　+8　h.　At　this　time,　the　tensile　strength　of　the　alloy　was　330　MPa　and　the　elongation　was　5.34%.　©　2024　Chinese　Mechanical　Engineering　Society.　All　rights　reserved.
