先进材料焊接现状及进展 Present situation and progress of welding for advanced materials 李亚江 LI Yajiang 1 first-author 山东大学 山东大学 Shandong University Shandong University 随着现代科学技术的发展,对焊接质量及结构性能的要求越来越高,各种先进及特殊材料的焊接近年来不断涌现。先进材料极大的推动了科学技术进步和社会发展,并在电子、能源、车辆制造、航空航天、核工业等部门中得到了应用。先进材料的焊接涉及面很广泛,其主要特点是高性能、高硬度、焊接难度大,受到人们的关注。仅以先进陶瓷、金属间化合物、C/C复合材料为例,阐述先进材料特种焊接现状及研究进展,对推进先进材料焊接研究及发展有一定的意义。 The requirements for welding quality and structural performance are getting higher and higher with the development of modern science and technology. All kinds of advanced and special materials continue to emerge in recent years. Advanced materials have greatly promoted the progress of science and technology and social development, and have been applied in electronics, energy, vehicle manufacturing, aerospace and nuclear industry. The welding of advanced materials involves a wide range of areas because they have some characteristics of high performance, high hardness and welding difficulty. Present situation and research progress of special welding of advanced materials is clarified with the example of advanced ceramics, intermetallics and C composites, which has a certain significance for promoting the research and development of advanced materials welding. 先进材料 特种焊接 金属间化合物 C/C复合材料 Advanced materials Special welding intermetallic compounds C-C composites TB30;TG40 2022-03-08 9 50
