| 2 | 铝合金与镀锌钢板回填式搅拌摩擦点焊机制显示文摘目的研究铝合金与镀锌钢板回填式搅拌摩擦点焊界面组织演变机制与焊接工艺参数对力学性能的影响规律。方法采用连续焊接和改变焊接工艺参数的方法,分析了焊具自摩擦对焊接温度和接头力学性能的影响。采用电镜研究了铝合金与镀锌钢板连接界面的显微组织分布和焊接工艺参数对焊接温度及接头力学性能之间的内在关系。结果焊具的自摩擦及重复性预热影响焊具温度和接头力学性能,其作用远大于焊接工艺参数的影响。镀锌层阻止了被焊材料的直接接触而避免了大量金属间化合物的形成,镀锌层和铝合金反应生成固溶体组织,从而提高了铝合金与钢的焊接性。此外,液态的锌被挤出搅拌区,形成钎焊的连接机制,增大了接头连接面积和强度。最佳焊接工艺参数为:旋转频率1800 r/min,套筒下压量1.0 mm,停留时间3 s。在此焊接规范下,接头最大接头剪切强度为6.23 kN,且76.2%的焊点力学性能满足工业使用标准。结论回填式搅拌摩擦点焊是实现铝合金与镀锌钢板高质量连接的可靠方式。 | 申志康 刘小超 陈海燕 李文亚 DING Yuquan CHEN James GERLICH Adrian | 2019 | 精密成形工程2019，11，6： | 1 |

| 4 | Refill Friction Stir Spot Welding Al Alloy to Copper via Pure Metallurgical Joining Mechanism显示文摘The current investigation of refill friction stir spot welding(refill FSSW)Al alloy to copper primarily involved plunging the tool into bottom copper sheet to achieve both metallurgical and mechanical interfacial bonding.Compared to conventional FSSW and pinless FSSW,weld strength can be significantly improved by using this method.Nevertheless,tool wear is a critical issue during refill FSSW.In this study,defect-free Al/copper dissimilar welds were successfully fabricated using refill FSSW by only plunging the tool into top Al alloy sheet.Overall,two types of continuous and ultra-thin intermetallic compounds(IMCs)layers were identified at the whole Al/copper interface.Also,strong evidence of melting and resolidification was observed in the localized region.The peak temperature obtained at the center of Al/copper interface was 591℃,and the heating rate reached up to 916℃/s during the sleeve penetration phase.A softened weld region was produced via refill FSSW process,the hardness profile exhibited a W-shaped appearance along middle thickness of top Al alloy.The weld lap shear load was insensitive to the welding condition,whose scatter was rather small.The fracture path exclusively propagated along the IMCs layer of Cu_(9)Al_(4) under the external lap shear loadings,both CuAl_(2) and Cu_(9)Al_(4) were detected on the fractured surface on the copper side.This research indicated that acceptable weld strength can be achieved via pure metallurgical joining mechanism,which has significant potential for the industrial applications. | Zhikang Shen Yuquan Ding Wei Guo Wentao Hou Xiaochao Liu Haiyan Chen Fenjun Liu Wenya Li Adrian Gerlich | 2021 | Chinese Journal of Mechanical Engineering2021，34，4： | 0 |
