本文研究了超细晶(UFG)2级钛在Conform SPD和旋转锻造(RS)机上机械加工后的退火对力学性能和组织性能的影响。本研究的主要目的是优化热处理制度，以实现严重变形的组织的回复，同时保持被加工材料的力学性能。用膨胀法测定了恢复过程的温度。研究发现，在超细晶材料中，回复过程的温度向较低的值移动。在膨胀分析的基础上，制定了退火制度，并对力学性能和组织性能进行了评估。
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.
