摘要: 超声强化技术可用来改善材料表面完整性以提高其疲劳性能。本文针对超声滚压强化对低合金高强钢疲劳性能的影响进行研究，通过分析超声强化的强化机理及疲劳试样实验，采用金相显微镜、微观硬度仪及扫描电镜对30CrMnSiNi2A疲劳试样进行微观结构及显微硬度的测试，结果表明，经过超声强化后试样表面出现一层强化层，组织更为细密，显微维氏硬度与未表面强化的试样相比提高了9.8%。在1 400 MPa应力作用下，30CrMnSiNi2A高强钢试样的疲劳寿命较传统抛光下的试样增加了38.4%。Abstract: Ultrasonic strengthening technology can be used to improve the surface integrity of materials in order to increase the fatigue life. The effect of the ultrasonic rolling strengthening on the fatigue property of high-strength steel was studied. Metallographic microscope, microhardness tester and scanning electron microscope were utilized to analyze microstructure and microhardness of the strengthened specimens, and the results showed that the strengthened layer can be obtained after ultrasonic strengthening treatment, and the microstructure become finer, the microhardness can be improved by 9.8% as well. At the same time, the fatigue life of the 30CrMnSiNi2A high-strength steel can be increased by 38.4% comparing with the polished specimens at a test stress of 1 400 MPa.
