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 Ti 2 Bi phase has been confirmed. Some formerly unknown binary phases (TiBi, Ti 2 Bi 3 , TiBi 2 ) have been observed. The phase TiBi is, probably, identical with Ti 8 Bi 9 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.
