(Ultrasonic impact treatment, UIT)作为改善焊接接头性能的全新技术,可以有效降低接头应力集中程度,调整接头残余应力场,减小或消除表面微观缺陷,在提高钢铁材料,铝合金,钛合金焊接接头的耐腐蚀性,疲劳性能等方面得到深入的研究[12-16].但关于超声冲击处理对MB8镁合金焊接接头组织性能的影响研究较少.本文作者对未超声冲击处理和不同工艺参数超声冲击处理MB8镁合金焊接接头的显微硬度...可在垂直于焊缝的方向做适当角度的摆动,以使焊趾区的几何外形为光滑圆弧过渡. 图4 HJ-III型超声冲击处理设备 Fig. 4 HJ-III type ultrasonic impact treatment equipment 1.4 金相组织及硬度试验 采用德国ZEISS公司生产的Axio Vert.A1型倒置万能金相显微镜对冲击和未经超声冲击处理的MB8镁......
%Al-0.5%Zn(wt%) anodes for Mg-air batteries are systematically investigated in3.5 wt% Na Cl solution. The external field treatment particularly the variable-frequency ultrasonic field can dramatically refine the α-Mg grains and μ phases. The grain size decreases from 1594.8 ± 43 μm(untreated billet) to 140.6 ± 15 μm after variable-frequency ultrasonic field treatment. The values of open circuit......
