| Abstract Scope |
A greater understanding has emerged over recent years on the formation of macrozones or mictrotextured regions of similarly oriented alpha particles and specially textured beta grains that form under certain conditions of processing of titanium alloys. This new dimension of structure has important effects on crystal plasticity and mechanical behaviour of titanium alloys. The evolution of structure during hot processing results from interplay between deformation texture of alpha and beta phases, and transformation textures arising from the alpha to beta and the reverse beta to alpha transformation. We review the current status of this understanding and complement it with more recent results on the relationship between the initial distribution of alpha variants and the distribution after compression in the alpha + beta phase field in a set of three alloys with different beta equivalent contents. We also pay special attention to the evolution of grain boundary alpha during processing. |
