【摘要】 综述了金属基复合材料中增强体/基体(R/M)界面接合类型,对比了焊接条件下与制备条件下R/M界面结合特征的差别。据此首次提出将界面分为一次界面与二次界面的分类方法;进而提出了钎焊与液相扩散焊热循环中R/M界面演变行为模式,即一次界面的损伤/解体与二次界面的重建。讨论了R/M界面演变行为及其对接头强度的直接与间接影响。更多还原

【Abstract】 The types of reinforcement/matrix(R/M) interface bonding in metal matrix composite(MMC) were reviewed,and the differences in the interfacial bonding characteristics between prior-joining and post-joining were compared.Based on above analysis,the interface was classified into the primary interface and secondary interface;then the interface evolution model during the thermal cycle in brazing and transient liquid phase bonding was proposed,which consists of the damage/failure of the primary interface and the restoration of the secondary interface.Furthermore,the interface evolution behavior and its direct and indirect effects on joint strength were discussed.更多还原
