Abstract

This paper describes a vertical section Ti-27.5Al 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 α2, 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.
