Abstract
The evolution of the Ti–Zr alloy microstructure (residual stresses, as well as microstress) during annealing after severe plastic deformation is reported. A strong residual macro-stresses relief starts at temperature of 530–540°C. A steep decrease continues up to 580°C and a further slight decrease up to 600°C. Microstrain (caused by the high dislocation density created by equal channel angular pressing) is almost constant up to 300°C, and then begins to decrease gradually due to recovery. The microstrain decrease accelerates at 560°C and is finished at 580°C. Most probably, this is caused by recrystallization. The information obtained is important for possible microstructure modifications and tuning via post-process heat treatment.
