Effects of single-side and double-side friction stir processing on microstructure and properties of Mg-Zn-Y-Nd alloy thick plate

  • 摘要: 为了获得组织分布均匀且综合性能好的较大改性区,对Mg-Zn-Y-Nd合金厚板进行单面和双面搅拌摩擦加工,并对其组织和性能进行研究。结果表明:经搅拌摩擦加工后合金的微观组织均得到了显著细化,单面和双面搅拌摩擦加工后合金搅拌区的上部、中部和下部样品的平均晶粒尺寸依次分别为4.45 μm、5.08 μm、5.30 μm和3.93 μm、3.20 μm、3.19 μm;相比于均匀化退火态合金和单面搅拌摩擦加工态合金,双面搅拌摩擦加工态合金的组织分布更加均匀和细小,其下层搅拌区的抗拉强度和伸长率最高,分别为283.3 MPa和23.9%,且耐腐蚀性能最好,腐蚀方式由点蚀变为均匀腐蚀。
