Abstract

Recrystallization during hot compression of the Ti5553 alloy in the two-phase α+β regime has been studied with the help of fine scale, orientation image mapping techniques. We find two distinct recrystallization processes. The first is associated with the well-known α globularisation process, and results in the loss of the Burgers orientation relationship between α and β, with the consequent randomization of the of the sharp, starting transformation texture. An alternative, dynamic recrystallization process is also observed in which newly recrystallized α and β grains form with the Burgers orientation relationship with each other. We call this epitaxial recrystallization.
