Recrystallization in β brass

Abstract

Recrystallization has been studied in Β brass in order to evaluate the influence of order on the recrystallization process. Recrystallization takes place by the formation of new grains at shear band - grain boundary intersections followed by grain growth and coalescence. Recrystallization occurs most readily at temperatures near the critical ordering temperature where the alloy has partial or short-range order and this is because both new grain formation and grain growth are fastest. Dislocation recovery processes are more difficult within the partially ordered materials and a larger strain energy is retained to drive recrystallization.
