【 摘 要 】

Investigation results of microstructure influence on oxidation coefficient during chemical-heat treatment of V-Cr-W-Zr alloy are presented. It is shown that the formation of a high defect structural state in the alloy leads to a twofold increase in the oxidation coefficient and a significant increase in the oxygen concentration. The maximum effects of the microstructure on the oxidation processes are detected at short treatment times.
