摘要：

The characteristics of the relaxation and recrystallization processes in pure tantalum deformed by rolling at room temperature are studied. It is established that at 800°C the recovery processes are activated and nuclei of recrystallization grains appear. After 1000°C, an activation of primary recrystallization is observed, which, after annealing at 1200°C, involves the entire material volume. It is shown that the processes of structural relaxation beginning at 800°C are accompanied by a dramatic decrease in microhardness.
