焊速对AZ80镁合金搅拌摩擦焊接头成形及组织的影响
Effect of Welding Rates on Friction Stir Welded Joint Shaping and Microstructure of AZ80 Magnesium Alloy
摘 要
采用搅拌摩擦焊工艺对AZ80镁合金进行焊接, 在其它工艺参数不变的条件下, 研究了焊接速度对接头成形及组织的影响。结果表明: 在搅拌头旋转速度为1 000 r·min-1、焊接速度为150 mm·min-1时可获得表面无缺陷、内部无孔洞的致密焊缝; 焊速越大, 焊核区前进侧中部组织中的动态再结晶晶粒越细小, 焊速对热机影响区和热影响区组织的影响基本相同。

Abstract
Friction stir welding was adopted to weld AZ80 magnesium alloy, the effects of welding rates on friction stir welding joint shaping and microstructure were studied under the condition of other parameters unchanging．The results show that the good surface quality and compact weld seam were obtained when the rotation rate was 1 000 r·min-1 and the welding rate was 150 mm·min-1. The dynamic recrystallization grains in the medium of advancing side of nugget zone decreased with the increase of welding rate, and the effect of welding rate on microstructure of thermo-chemical affected zone and heat affected zone was no difference.
