Evolution of Microstructure and Texture during Annealing in a High-Pressure Torsion Processed Fe-9Cr Alloy
Abstract
The microstructure and texture of a Grade 91 (Fe-9Cr)alloy, which were subjected to high-pressure torsion (HPT)and annealing at 600 °C, were investigated. The HPT significantly refined the grain size, and generated typical body-centered cubic (bcc)torsion textures, including J{110} < 211> , D{112} < 111 > and E{011} < 111 >. During annealing, grains grew, and J became the most important texture component. Grains orientated in J showed increased number density and larger average grain sizes in the annealed microstructure. The dominance of J can be explained based on the stored energy and grain boundary characteristics of the J grains.
