For Mo-47%Re-0.4%Zr alloy in a polygonized state low temperature internal oxidation was carried out. Aimed to estimate an enhancement of heat resistance the thermal stability of dispersion hardened alloy was studied in the process of heat treatment at the temperatures about 2473 K. It was revealed that internal oxidation results in precipitation of ZrO2 particles predominantly on substructural defects. Oxide particles stabilize dislocations and promote recrystallization suppression up to 2473 K. High oxygen solubility in the alloy was found at 1573 K.
