讨论了镁合金AZ6 1在摩擦焊 (FSW)过程中的显微组织演变过程 ,以及显微组织与机械性能的关系 ;镁合金AZ6 1焊件的拉伸性能受结晶取向分布、颗粒大小和位错密度等因素的强烈影响
The microstructure evolution of magnesium alloy AZ6 1 during friction stir welding (FSW) was discussed, and the relationship between microstructure and mechanical properties was discussed. The tensile properties of magnesium alloy AZ6 1 weldment were affected by the crystal orientation distribution, particle size and position The density and other factors of strong influence
