Effect of introduced oxygen concentration on thermal stability of internally oxidized V–Cr–Zr alloy

The thermal stability of the internally oxidized V-Cr-Zr alloy was studied depending on the concentration of oxygen introduced during chemical-heat treatment. It was found that an increase in the oxygen concentration from 0.65 to 1.34 at.% promotes an increase in the temperature of the primary recrystallization start from 0.7Tmelt to 0.85Tmelt. It was shown that as the value of the stoichiometric ratio coefficient increases, not only does the activation temperature of primary and secondary recrystallization shift to the region of higher temperatures, but also, in contrast to classical concepts, a tendency toward almost simultaneous implementation of these processes is observed. Thus, the use of chemical-heat treatment to increase the thermal stability of the V-Cr-Zr alloy by 300 degrees or more is experimentally substantiated.
