| Abstract Scope |
During the transformation from hcp alpha to bcc beta, upon the use of slow enough heating rates, the latter phase may grow epitaxially from existing bcc particles and consume the former. Therefore the texture of the high temperature beta phase depends directly on the set of discrete orientations existing in the parent metal prior to heat treatment. Large regions of similarly oriented primary alpha particles, or microtextured regions, are found in most forging billet. It has recently become apparent that the orientation of the beta phase may also be nearly constant over similarly large regions. This work explores whether differences in grain growth kinetics during beta annealing can be attributed to the texture of the beta phase and its spatial arrangement prior to heating. |
