中文摘要：

本工作提出一种新的辐照损伤合金化方法，首先采用离子注入技术将离子束注入金属，使其产生包括空位在内的辐照损伤，然后利用辐照损伤来诱发互不固溶金属之间的扩散和合金化，从而实现金属界面之间的冶金结合．扩散层中形成的非晶合金相是形成冶金结合的关键．基于该辐照损伤合金化机制，制备出了高性能的空间飞行器太阳能电池阵互连片用Mo／Ag层状复合材料，这种材料与空间GaAs电池片的单点电阻点焊拉伸强度最高达到了150MPa，平均为130MPa，超过了国家军用标准和航天用户提出的指标要求．

英文摘要：

The preparation of laminar metal matrix composites for immiscible alloy systems was difficult due to the positive formation heat and diffusion difficulty between each other, resulting in no metallurgy combination forming on interfaces. Aiming at this situation, a new irradiation damage alloying method for immiscible and not reacting alloy systems was presented in this work, through irradiation damages were produced by an ion implantation technology in the matrix metal first, and then the metal in the surface layer diffused into the matrix metal through the irradiation damages to form metallurgy combination with the metal. The key of this kind of metallurgy combination is to form amorphous alloy phase in the diffusion layer. By alloying the high-performance Mo/Ag laminar metal matrix composites used in spacecraft were prepared, whose maxium resistance spot welding joint tensile strength reaches 150 MPa, the average 130 MPa. The properties of thees composites exceed the national military standards and the technical requirements specified by astronic users.
