Abstract：

Effects　of　Nd　addition　including　0,　1%,　2%,　3%,　on　microstructure　and　ambient　and　elevated　mechanical　properties　of　Mg-4A1-1S　alloy　have　been　investigated.　It　is　found　that　the　mechanical　properties　of　the　alloy　with　Nd　addition　can　be　significantly　improved　as　a　result　of　the　refinement　of　grain　size　and　creation　of　acicular　high　melting　point　Al11　Nd3　phase.　The　ambient　and　elevated　tensile　strength　of　the　alloy　reaches　206　MPa　and　138　MPa,　respectively,　with　2.　0%　Nd　addition,　compared　with　that　of　alloy　with　out　Nd　addition,　increased　by　20　%　and　14　%,　respectively.　With　the　further　increase　of　Nd　addition,　the　mechanical　properties　of　the　alloy　are　deteriorated　due　to　the　creation　of　bulk　Al2　Nd　phase　in　the　alloy.
