Abstract
The phase equilibrium of annealed Ti-Nb-Sn alloys was investigated by means of x-ray diffraction, scanning electron microscopy and electron probe microanalysis. Isothermal section of the Ti-Nb-Sn ternary system below 50 at.% Sn at 700 °C was constructed according to the examinational analysis. The compositions of α-Ti, β(Ti, Nb), Ti3Sn, Nb3Sn and Ti3Nb3Sn2 were confirmed. The solubility of Sn in β(Ti, Nb) region reaches up to 9.2 at.%, which is a relative large solubility, and that in α-Ti is small. The solubility in Ti3Sn reaches up to 14.9 at.% Nb, and that of Nb3Sn is 21.5 at.% Ti. The solubility range of Nb and Sn in Ti3Nb3Sn2 is approximately 26.2-39.5 and 22.6-26.6 at.%, respectively.
