摘要：
Two Nb-Mo-Ti alloys were modified by additions of 2 at.% Fe. These small additions of Fe did not form secondary phases but noticeably increased the strength of the Nb-Mo-Ti alloys in the temperature range of 25 to 1200 degrees C due to solid solution strengthening effect. The oxidation resistance at 1200 degrees C in air was also improved considering both oxidation kinetics and the fraction of retained, un-oxidized metal alloy.
