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 physical, chemical and mechanical properties of metallic materials (such as Mg, Al, Ti and their alloys) and reinforcing components (carbon fibers, SiC whiskers, particles, etc.) used in metal matrix composites vary greatly and they are integrated into one As a structural material, it has become a very important new field in material science. From the welding discipline perspective, the study of the connection technology of microstructural heterogeneous materials existing inside the composite material is not only important to the mechanical properties and composite technology of the composite material Significance, the composite materials (plates, rods, tubes, etc.) practical, it is also of practical significance welding with other materials.
