| Abstract: | Multiphase Mo-Si-B system are candidate materials for ultra-high temperature applications. Mo-Si-B silicides consisting of the phases α-Mo（Mo solid solution）, Mo3Si, and Mo5SiB2 （T2） have melting points on the order of 2000 ℃. As a good candidate structure material for aircraft engines and protective coating, Mo-Si-B system alloy exhibites outstanding high temperature mechanical properties and oxidation resistance. In this paper, the preparation, oxidation resistant and fracture toughness are reviewed. Lastly, the future development in Mo-Si-B system alloys is also discussed. |
