摘要

采用超声冲击（UIT）技术对在役12Cr1MoV钢焊接接头表面进行强化处理，分析了不同冲击参数下接头表面形貌、表层微观组织及硬度分布特征，并利用透射电子显微镜（TEM）、电子背散射衍射（EBSD）技术对接头表面变形层的组织演化进行分析。结果表明：超声冲击处理能够改善服役态12Cr1MoV钢焊接接头焊趾区几何形貌并提高焊趾处几何过渡半径和焊趾处硬度值，相较未冲击试样，当采用UIT1和UIT2冲击参数处理时，焊趾处过渡半径分别提高了108.2%和116.4%，相应地，焊趾处硬度平均值分别增加了32.3%和34.9%（距表面0.1 mm深度内）。此外，通过试验证实超声冲击处理能够在服役态12Cr1MoV钢焊接接头表层引入梯度纳米晶结构层，且晶粒发生纳米化主要依靠位错滑移方式实现。

Abstract

In this paper, ultrasonic impact treatment (UIT) technology was used to strengthen the surface of 12Cr1MoV steel welded joints in service. The changes in surface morphology, microstructure, and microhardness under different treatment parameters were analyzed. The evolution behavior of the deformed layer on the surface of the sample was compared and analyzed using transmission electron microscopy (TEM) and electron backscatter diffraction (EBSD) techniques. The results show that ultrasonic impact treatment can improve the geometric morphology of the weld toe area of 12Cr1MoV steel welded joints in service, and increase the geometric transition radius and hardness value at the weld toe. Compared to the as-received sample, when using UIT1 and UIT2 parameters, the transition radius at the weld toe increased by 108.2% and 116.4%, respectively. Correspondingly, the average hardness at the weld toe increased by 32.3% and 34.9%(within a depth of 0.1mm from the surface). In addition, it has been confirmed through experiments that ultrasonic impact treatment can introduce a gradient nanocrystalline structure layer on the surface of the welded joint of 12Cr1MoV steel in service, and the nanocrystallization of the grains is mainly achieved through dislocation slip.
