摘要：

The　precipitation　hardening　of　dilute　Al-Er,　Al-Zr　and　Al-Er-Zr　alloys　was　investigated　by　microhardness　measurements　and　transmission　electron　microscopy.　The　Al-0.04Er　(at.%)　alloy　obtains　its　maximum　aging　hardness　of　400　MPa　due　to　the　precipitation　of　Al(3)Er.　The　Al-0.04Er-0.08Zr　obtains　a　maximum　hardness　of　560　MPa,　which　is　significant　greater　than　that　of　the　Al-Er　and　Al-Zr　alloys.　The　synergetic　effect　of　Er　and　Zr　on　the　precipitation　hardening　of　Al-Er-Zr　alloys　is　discussed.　(C)　2011　Acta　Materialia　Inc.　Published　by　Elsevier　Ltd.　All　rights　reserved.
