    摘要:

    研究了SiCp/A356復(fù)合材料非真空半固態(tài)攪拌釬焊過(guò)程。在一定的攪拌釬焊條件下，重點(diǎn)研究了釬料的固相率對(duì)接頭的微觀結(jié)構(gòu)、線(xiàn)結(jié)合率和強(qiáng)度的影響規(guī)律。研究結(jié)果表明：在攪拌條件下，半固態(tài)釬料固相率對(duì)基體氧化膜的破碎有重要影響；隨著釬料固相率的增加，接頭界面的線(xiàn)結(jié)合率和接頭的強(qiáng)度先增加后減小；在釬料固相率為60%時(shí)，接頭界面線(xiàn)結(jié)合率和接頭強(qiáng)度同時(shí)達(dá)到最大值，分別為91.2%和160 MPa。

    Abstract:

    The vacuum-free semi-solid stirring brazing process of SiCp/A356 composites was investigated. Under a certain stirring and brazing condition, the effects of the solid fraction in filler metal on the microstructure, bonded ratio and the tensile strength of bonded joints were investigated. Results show that with stirring the solid fraction of the semi-solid filler metal has a significant influence on the break of the substrate oxide film. And, with increasing of the solid fraction in filler metal, the bonded ratio of the interface and the tensile strength of the bonded joints increases, until up to the maximum values of 91.2% and 160 MPa respectively when the solid fraction is 60%; afterwards they start to decrease. At that time, a good bond between filler metal and composites appears.
