摘要：

The　Mg-Zn-Gd　icosahedral　quasicrystal　master　alloy　particles　was　added　into　the　AZ31　alloy　by　the　repeated　plastic　working　(RPW)　process　in　order　to　produce　AZ31　based　composite　reinforced　by　the　icosahedral　phase.　The　wear-resistance　of　the　alloys　and　compositions　under　a　lower　load　were　investigated.　The　results　show　that　the　distribution　of　reinforcement　in　the　composite　with　10%　(mass　fraction)　quasi-crystal　master　alloy　is　significantly　uniform.　The　wear　coefficient　of　the　AZ31　alloy　and　composites　decreases　as　the　load　increases.　On　the　whole,　the　addition　of　high-stable　and　high-hard　icosahedral　quasicrystal　leads　to　obvious　improvement　of　wear-resistance　property.　©　2016,　Central　South　University　of　Technology.　All　right　reserved.
