| 摘 要： | 研究轴向力对搅拌摩擦焊接AZ61A镁合金拉伸性能的影响。在3～7kN范围内选择5个不同大小的轴向力制备接头。测试接头的拉伸性能,并研究其与搅拌区显微组织和硬度的相关性。结果表明,与其他轴向力下的接头相比,轴向力为5kN时制备的接头具有最好的拉伸性能。搅拌区生成的细晶组织和高硬度是获得高拉伸强度的主要原因。

| Abstract: | The influences of axial force on tensile properties of friction stir welded AZ61A magnesium alloy were studied.Five different values of axial forces ranging from 3 to 7 kN were used to fabricate the joints.Tensile properties of the joints were evaluated and correlated with the stir zone microstructure and hardness.From this investigation,it is found that the joint fabricated with an axial force of 5 kN exhibits superior tensile properties compared to other joints.The formation of finer grains in the stir zo... |
