| 摘 要： | The oxidation behaviors of Nb67-xW15Si18Hfx （x=0, 5, 10） alloys were studied at 1 250 ℃ in air. It is found that the Nb67W15Si18 alloy has the best oxidation resistance among the three alloys; and Hf addition is harmful to the oxidation resistance of the Nb67W15Si18 alloy. The oxides formed on the Nb67W15Si18 alloy are mainly Nb12WO33 and NbO2, and that on the Nb62W15Si18Hf5 and Nb57W15Si18Hflo alloys is Nb2O5. Effect of Hfon the oxidation behavior of the Nb67-xW15Si18Hfx alloys has been discussed based on mierostructures and kinetics of oxidation.
