Preparations and Applications of Intermetallic Compounds

Intermetallic compound is being considered as a material for high temperature applications due to the combination of its many excellent properties such as low density,high melting temperature and high temperature strength. Here,several preparation techniques of intermetallic compounds,for example, mechanical alloying,self-propagating high-temperature synthesis, spark plasma sintering and directional solidification method are reviewed.The present status and applications in various fields as well as the prospects of intermetallic compounds are presented too. It's indicated that in order to enlarge the applications areas, people should intensify not only the investigation of theories but also the research on preparation methods and processes which influence on the structure and performance of materials.At the same time,a further study for optimizing the processing parameters is required to improve the property of materials.
