摘要

    摘要
  • 摘要: 采用恒压力控制方式对4 mm厚1561新型高镁铝合金板材进行了搅拌摩擦焊接试验，并对焊接过程中搅拌头压力特征、接头微观组织以及力学性能进行了研究. 结果表明，焊接下扎阶段下压力呈先上升后下降再上升的趋势. 稳定焊接阶段，由于材料力学性能的周期性变化导致下压力呈近似正弦周期性变化. 固定焊接速度为200 mm/min，当转速低于800 r/min或高于1 800 r/min时，焊缝产生孔洞缺陷. 当转速超过1 000 r/min时，搅拌区产生"S"线. 接头抗拉强度在低转速时主要受接头金属强度影响，高转速时主要受"S"线分布特征影响. 随搅拌头转速的增加，接头抗拉强度先上升后下降.
    Abstract: 4 mm thick 1561 aluminum alloy was friction stir welded by the constant pressure controlling mode. The characteristics of the welding pressure, the microstructures and the mechanical properties of the joints were studied. The results indicated that in the plunging stage, the welding pressure alternately experienced increase, decrease and then increase. In the stable welding stage, the welding pressure changes as a sinusoidal periodic trend induced by the variation of the mechanical property of the welded metal. Fixed the welding speed at 200 mm/min, when the rotation speed is lower than 800 r/min or higher than 1 800 r/min, the void defect formes in the weld. When the rotation speed is higher than 1 000 r/min, the "S" line appeares in the stir zone. The tensile strength of the FSW joint is depended on the material strength of the joint when the rotation speed is relatively low. When the rotation speed is relatively high, the "S" line has significant effect on the tensile strength of the FSW joint. With the increase of the rotation speed, the tensile strength of the joint firs increases and then decreases.
