DEVELOPMENT AND EVALUATION OF HIGH-TEMPERATURE TUNGSTEN ALLOYS. Quarterly Report No. 1, October 1, 1959-December 31, 1959
High-W alloys were prepared by powder metallurgy techniques. Room- temperature strength properties were determined for W--Ni--Fe compositions with quaternary additions of Cr, Pd, and Ru; at W levels of 80 to 94 wt%. Small (1 to 3 wt%) Ru additions were the most effective in improving strength. The oxidation resistance of a number of W-base alloys was measured at 2000 deg F. Quaternary W- Ni--Fe base alloys containing Al, Ru, Ti, and Zr were the most oxidation resistant, having values similar to unalloyed W. Oxidation protection of a 90W-- 6Ni --4Fe material was accomplished by a fused coating of AMS 4775; the composite was tested for 482 hr in air at 2000 deg F without damage to the base alloy. (auth)
