Phase formation on the sintering of MoSi2 powder by Ni addition
- Molybdenum disilicide has high melting point (approximately 2020°C), low density (6.27 g/cm3) relative to some metals, and excellent high temperature oxidation resistance. Because of its high ductile-brittle transition temperature and low fracture toughness at room temperature 1, 2, 3, 4, 5, 6, 7, 8, 9, however, it is required to be sintered at high temperature to attain full densification [2]. There has been little work performed on the pressureless sintering of MoSi2. Recently, it has been reported that the MoSi2 sintering process is controlled by the diffusion of molybdenum and it needs to be sintered over 1800°C at which the sintered density was more than 90% of theoretical density [10].
