Microstructure,　texture,　and　mechanical　properties　of　the　extruded　Mg–2.49Nd–1.82Gd–0.2Zn–0.2Zr　alloy　were　investigated　at　different　extrusion　temperatures　(260　and　320°C),　extrusion　ratios　(10:1,　15:1,　and　30:1),　and　extrusion　speeds　(3　and　6　mm/s).　The　experimental　results　exhibited　that　the　grain　sizes　after　extrusion　were　much　finer　than　that　of　the　homogenized　alloy,　and　the　second　phase　showed　streamline　distribution　along　the　extrusion　direction　(ED).　With　extrusion　temperature　increased　from　260　to　320°C,　the　microstructure,　texture,　and　mechanical　properties　of　alloys　changed　slightly.　The　dynamic　recrystallization　(DRX)　degree　and　grain　sizes　enhanced　as　the　extrusion　ratio　increased　from　10:1　to　30:1,　and　the　strength　gradually　decreased　but　elongation　(EL)　increased.　With　the　extrusion　speed　increased　from　3　to　6　mm/s,　the　grain　sizes　and　DRX　degree　increased　significantly,　and　the　samples　presented　the　typical　＜21¯1¯1＞−＜112¯3＞　rare-earth　(RE)　textures.　The　alloy　extruded　at　260°C　with　extrusion　ratio　of　10:1　and　extrusion　speed　of　3　mm/s　showed　the　tensile　yield　strength　(TYS)　of　213　MPa　and　EL　of　30.6%.　After　quantitatively　analyzing　the　contribution　of　strengthening　mechanisms,　it　was　found　that　the　grain　boundary　strengthening　and　dislocation　strengthening　played　major　roles　among　strengthening　contributions.　These　results　provide　some　guidelines　for　enlarging　the　industrial　application　of　extruded　Mg–RE　alloy.　©　University　of　Science　and　Technology　Beijing　2025.
