摘要
The isothermal sections of the Nb Ti Si ternary system at 1?473?K and 1?373?K were determined by means of diffusion triple technique and electron microprobe analysis. By analyzing the diffusion layers in the diffusion couples, the titanium silicides and niobium silicides forming in this system were identified. The results show that no ternary compounds formed in the Nb Ti Si ternary system at the test temperatures. The phase transformations occurring on cooling from 1?473?K to 1?373?K were discussed.
