摘要：
The possibilities of using reversible hydrogen doping in combination with warm rolling for milling the structural components and the formation of a heterophase structure are shown by the example of the VT6 alloy. Alloy doping with 0.3-0.7 wt % hydrogen and the formation of a alpha + beta + alpha(2) structure is accompanied by the enhancement of the local nonuniformity of deformation and an increase in the number of recrystallization nuclei during warm sheet rolling. The relation between the initial hydrogen concentration and the temperature of vacuum annealing (VA) with the phase composition and the size of structural components is established.
