摘　　要：金属基复合材料中应用的金属材料(Mg、Al、Ti及其合金等)与增强组元(碳纤维、SiC晶须、颗粒等)的物理、化学、力学性能相差极大,将它们复合成一整体作为结构材料使用,成为当今材料科学内极为重要的新领域,从焊接学科角度,对复合材料内部存在的微结构异质材料的连接技术加以研究,不但对复合材料力学性能及复合工艺有直接重要意义,对复合材料(板、棒、管等)实用化时,它与其它材料的焊接也有实际意义.The metal materials (Mg, Al, Ti and alloys) and the reinforcing components (Carbon fiber, SiC whiskers, particles, etc.) used in forming metal matrix composites have great mismatch between their physical, chemical and mechanical properties. The study of fabricating Al/C fiber composites and using them as structural materials is becoming an important new field in material science. An investigation on the microstracture bonding technology is not only of great significance for the improvement of mechanical property and fabricating process of the composites but also of great importance to the bonding of composite to composite or to other materials in the foreseeable practical applications.
