Effects of Surfactants on the Thermal Stability of the Mechanosynthesized Ti5Si3Cx Phase
摘要
Abstract
The effects of stearic acid and graphite additives during mechanical alloying of titanium and silicon in petroleum ether on the structural-phase state and stability of titanium carbosilicide during annealing at temperatures below 1300°C are considered. It is shown that the barrier layers on particles formed in the presence of surfactants increase the stability of carbosilicide more efficiently than in the presence of graphite. Surfactant additions lead to the formation of an additional silicon-containing phase and more efficient sintering of particles.
