| Abstract: | The potential synthesis method as hot-press, HIP, MA, reactive sintering is mainly introduced in this paper. It was pointed out that composite synthesis is effective way to improve the elevated temperature strength and low temperature ductile of MoSi 2.Crack deflection and grain boundary pinning are main mechanism of MoSi 2 compact reinforced respectively by whisker and particles. It is pointed out that finding out the relationship between the phase component and its property is helpful for the technology optimizing and systemizing. |
