- W152127590 abstract "The potential of Hf--Nb alloys as structural materials for use at high temperatures was evaluated. The work was conducted to determine the properties of Hf--Nb alloys and to select the more promising ones for further improvement. Properties determined were machinability, hardness, workability, tensile strength, and oxidation resistance. Ten ingots, rarging from 100% Nb to 70 at.% Hf, were prepared and subjected to tests. The test results showed that the alloys with 33 and 50 at.% Hf were superior in workability, strength, and oxidation resistance. For the alloy series tested, the strength and hardness values increased with the increasing Hf content. Maximum values were reached with 50 at.% Hf. The oxidation resistance was poorest at 1 at.% Hf but improved with increasing Hf content through 70 at.%. Eight of the 10 ingots were fabricable at room temperature. The two remaining ingots, those with 5 and 10 at.% Hf, required hot working. (auth)" @default.
