The work reported in this paper forms part of a larger investigation of the effects of microstructure on creep in a series of two phase {gamma}--TiAl based alloys. Here the authors examine a fully lamellar Ti-48Al-2Mn-2Nb alloy. They have attempted to quantify the microstructure in terms of a set of parameters, the most important of which are considered to be: colony size; perfection of the lamellar structure; lamella thickness; proportion of {alpha}{sub 2}; how serrated the colony boundaries are; and nature of the lamella interfaces.
