超聲沖擊對30CrMnSiNi2A鋼補焊接頭顯微組織和性能的影響
Effect of Ultrasonic Impact on Microstructure and Properties of 30CrMnSiNi2A Steel Repair Welding Joint
摘 要
對30CrMnSiNi2A鋼3次補焊接頭焊趾區域進行超聲沖擊處理,通過組織觀察、拉伸試驗、硬度測試和殘余應力測試等方法研究了超聲沖擊對補焊接頭顯微組織、力學性能和殘余應力的影響。結果表明:超聲沖擊使得在距離補焊接頭表面約100 μm區域產生晶粒細化和塑性變形;由于超聲沖擊影響層的厚度與補焊件相比較小,因此超聲沖擊對補焊接頭拉伸性能的影響不大;超聲沖擊使得補焊接頭表面的顯微硬度顯著提高,這與補焊接頭表面產生的晶粒細化和位錯運動阻力增大有關;超聲沖擊可將補焊接頭在多次補焊過程中累積的殘余拉應力轉化為殘余壓應力。

Abstract
The weld toe area of a three-time repair welding joint of 30CrMnSiNi2A steel was treated by ultrasonic impact. The effects of the ultrasonic impact on the microstructure, mechanical properties and residual stress of the repair welding joint were studied by microstructure observation, tensile test, hardness test and residual stress test. The results show that the ultrasonic impact caused grain refinement and plastic deformation in the area about 100 μm from the surface of the repair welding joint. The influence of ultrasonic impact on the tensile properties of the welding joints was small because the thickness of ultrasonic impact affected layer was smaller than that of the welding parts. The microhardness of the repair welding joint surface increased significantly by ultrasonic impact, which was related to grain refinement and the increase of dislocation movement resistance on the surface of the repair welding joint. Ultrasonic impact could transform the harmful residual tensile stresses accumulated in multiple repair welding into beneficial compressive stresses.
