摘要

采用搅拌摩擦焊机焊接6005A-T6铝合金挤压型材，借助力学拉伸试验机、显微硬度仪、光学显微镜、能谱仪和透射电镜探明了自然时效对其焊缝力学性能的影响规律.结果表明：6005A-T6铝合金搅拌摩擦焊缝随自然时效时间延长，其抗拉强度和焊缝焊核区的硬度均先提高并趋于稳定，而焊缝热影响区的硬度则保持不变，延伸率也变化不大；自然时效720 h后，焊缝达到稳定的自然时效状态；焊缝自然时效后其抗拉强度与焊核区硬度提高的主要原因是在自然时效过程中焊核区析出了较多细小且弥散的Mg

Si强化相.

Abstract

The 6005-T6 aluminum alloy extrusion profiles were obtained by friction stir welding. With the help of mechanical tensile test machine

Vickers hardness tester

optical microscope (OM)

energy dispersive spectrometer (EDS) and transmission electron microscopy (TEM)

the effect of natural aging on the mechanical properties of the welding joints is proven. The results shows that the 6005-T6 aluminum alloy with the extension of the natural aging time after welding

its tensile strength and the nugget zone (NZ) hardness increasing firstly and tending to be stable while the hardness of the weld heat affected zone (HAZ) remains unchanged and elongation changes a little. The FSW joints achieves the stable natural aging condition after natural aging 720 h. Natural aging impr

oves the tensile strength and the hardness of welding joints mainly because the nugget zone precipitates more small and dispersed Mg

Si phases in the process of natural aging.
