The evolution of annealing textures in a heavily-deformed bronze

Abstract

Texture analyses, supported by transmission electron microscopy, have shown that in a 10 pct tin bronze, texture changes do not take place until a considerable fraction of the heavily deformed material has recrystallized. Much of the “primary recrystallization” texture is, accordingly, made up of the (110)«112» component which has grown from the polygonized subgrains in the cold-worked metal. The “annealing textures” described in the literature initiate during the latter stages of primary recrystallization and evolve to significant proportions with grain growth. It is proposed that the “annealing textures” in low stackingfault energy (SFE) bronzes and brasses originate with the formation and growth of second-generation twins.
