✦ Synopsis

The system Ti-Bi-Sn has been investigated by solid/liquid diffusion couples at 500, 600, 700 and 800°C. A non-negligible solubility of Sn into solid Bi is found. Diffusion layers of the recently revealed ternary compound Ti 3 BiSn have been observed, thus its existence has been confirmed. Data about the homogeneity ranges of the binary end-system compounds have been obtained. The assessed growth constants of the diffusion layers are comprised in the interval 10 -12 -10 -14 m 2 .s -1 . The phases participating in the hypothetical ternary eutectic reaction, probably are: (Bi), (Sn), Liquid and Ti 2 Sn 3 .
