摘　　要：难互溶金属材料作为金属基复合材料的一种,其组元之间既不相互反应也不相互溶解,而阻碍其发展与应用。回顾了国内外难互溶金属材料及其复合界面的研究概况,以Cu-Fe、Mo-Cu为例介绍难互溶金属复合材料的特点、常用加工工艺及应用领域,研究表明,固相焊接可制备界面复合良好的难互溶复合材料,其结合处存在原子级的相互扩散区域。建立了难互溶材料的轧制复合与扩散焊接复合模型,为高效、优质制备难互溶复合材料提供指导依据。Low inter-solubility metal as a kind of metal matrix composites. The two bonding constituents are neither reaction nor dissolution in each other,which is against the development of composites. Research of low inter-solubility metallic composites in recent years is reviewed. This paper present the characteristics,applications and processing techniques of low inter-solubility metallic composites,both in China and abroad,using Cu-Fe and Mo-Cu as examples. It shows that atomic level interdiffusion was present at the interface,and low inter-solubility metal can be bonded by solid state welding. The model of roll-bonding and diffusion-bonding for low inter-solubility metal are established,which can provide a guidance for the processing of low inter-solubility metal with high quality and efficient.
