摘要
在780℃熔体反应温度下通过原位自生法生成Al3Zr/6082Al复合材料,使用XRD、SEM和TEM等分析测试技术研究其微观结构;利用搅拌摩擦焊接(FSW)对Al3Zr/6082Al复合材料进行焊接,观察和分析接头的微观组织和力学性能.结果表明:原位自生法制备的Al3Zr/6082Al复合材料主要由Al基体和Al3Zr增强相组成,复合材料组织较好.搅拌头转速为15000 r/min,200 mm/min下的FSW接头质量较好,焊缝强度较高.
Al3Zr/6082Al composite was synthesized by in-situ synthesis method at its melt-reaction temperature(780℃).The microstructure was analyzed by using the XRD,SEM and TEM.The friction stir welding(FSW)technology was used to weld the Al3Zr/6082Al composite.The microstructure and mechanical properties of the material of the weld zone was revealed.The results show that the main components of weld zone are the Al matrix and the Al3Zr reinforcing phase.The joint of the FSW weld zone has a good quality with high weld strength as the parameters(15000 r/min and 200 mm/min)were selected as the rotating speed of the mixing head.
