11/4/2019 Fe-ti Phase Diagram
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 2Bi phase has been confirmed. Some formerly unknown binary phases (TiBi, Ti 2Bi 3, TiBi 2) have been observed. The phase TiBi is, probably, identical with Ti 8Bi 9 reported previously. All intermediate phases suffer air corrosion, but in various degrees.
Al-Fe-Mn-Si phase diagram can be used to analyze the effects of Fe and Mn on the phase composition of casting Al-Si alloys of the 4XX.0 series. In many cases, this quaternary diagram solely makes it possible to answer the question as to which Fe-containing phases can be formed in a particular commercial alloy. Al-Fe-Si PHASE DIAGRAM.

A tentative variant of the Ti‐Bi phase diagram, including the newly found compounds, has been constructed. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim).
