摘要

本文研究了超声波对搅拌摩擦焊接接头显微硬度和显微结构的影响。研究发现，显微硬度最小的区域位于后退侧的热机械影响区。超声波冲击导致该区域面积增大。该区域的减弱主要归因于过时效导致的硬化颗粒含量较低。研究还发现，焊接过程中的超声波冲击使残余应力减少了 5 倍。

Effect of Ultrasonic Impact on the Microhardness and Microstructure of Friction Stir Welded Aluminum Alloy 2024

In this paper, the effect of ultrasound on the microhardness and microstructure of friction stir welding joints is investigated. It has been found that the area with minimum microhardness is located in the thermomechanically affected zone on the retreating side. An ultrasonic impact resulted in an increase in the size of this area. The weakening of the region is attributed primarily to the low content of hardening particles due to overaging. It was also found that the ultrasonic impact during welding resulted in a 5 times reduction of residual stresses.
