| Abstract: | The system Ti‐Bi has been investigated by solid/liquid diffusion couples at 400, 500, 600 and 700 °C. Indication that the growth rate of the diffusion layers at 500 °C is linear has been found, with a growth constant of around 5 × 10–11 m.s–1. The existence of the Ti2Bi phase has been confirmed. Some formerly unknown binary phases (TiBi, Ti2Bi3, TiBi2) have been observed. The phase TiBi is, probably, identical with Ti8Bi9 reported previously. All intermediate phases suffer air corrosion, but in various degrees. A tentative variant of the Ti‐Bi phase diagram, including the newly found compounds, has been constructed.
