【 摘 要 】

The present paper explores the effect of annealing on mechanical and structural properties of ultrafine-grained (UFG) Ti Grade 2 after it was mechanically worked in either CONFORM SPD or rotary swaging (RS) machine. The main objective of this study was to optimize the annealing schedule in order to achieve recovery in the severely deformed structure and at the same time retain the mechanical properties of the worked material. The temperatures of the recovery processes were determined by means of dilatometry. It was found that in an ultrafine-grained material the temperatures of the recovery processes are shifted towards lower values. Based on dilatometric analysis, annealing schedules were developed and mechanical and structural properties were evaluated.
