    摘要:

    對薄壁鋁合金/鋁基SiC復(fù)合材料搭接接頭微攪拌摩擦焊接(μ-FSW)工藝特性、接頭形貌特征及力學(xué)性能進行研究,并揭示搭接界面形成機制及接頭失效機制。結(jié)果表明：在較寬的工藝參數(shù)窗口內(nèi)均可得到成形良好的焊縫。由于μ-FSW所特有的金屬流動特點,以及SiC顆粒難以流動的特性,搭接界面呈現(xiàn)出一種特殊的“彎鉤狀”形貌。接頭的斷裂為界面遷移處 “減薄”區(qū)域的拉伸斷裂。接頭力學(xué)性能與載荷方向直接相關(guān),這是由不同的金屬塑性流動行為所致。

    Abstract:

    The micro friction stir welding (μ-FSW) of lap joint of thin Al-alloy plate with a thickness of 0.5mm and SiC reinforced Al composite were investigated, concentrating on the process characteristics, macro-morphology of weld cross-section and mechanical properties of the joints. The mechanisms of migration interface morphology formation and joint failure were revealed. The results show that with suitable indentation depth, wels of good appearance can be obtained in a wide range of process window. The weld cross-section shows a special “Hoop shape” migration interface morphology, caused by the characteristics of μ-FSW process and SiC particles. The joint failure mode is the tensile fracture of “thinning area” at the upper rim of migration interface. And the joint mechanical properties are directly related to the loading direction, which is caused by the different metal plastic flow behaviors under different loading directions
