摘要：

This payer describes a vertical section Ti-275.Al up to 25 at% Nb in the ternary Ti-Al-Nb system. This section is shown to be of fundamental importance in understanding the origin and relationship between the various phases which constitute the microstructures of an important class of engineering alloys based on the Ti3Al-Nb system, the alpha(2), B2 and O phases. In carrying out this work, the presence of two distinct forms of the O phase with the same space group and lattice periodicity, but different site occupations, has been confirmed.
