Description

Abstract: "Room-temperature properties were determined for W-Ni-Fe-Ru base alloys containing Cr, Mo, Pd, and Ta; highest strength levels were found in W-Ni-Fe-Ru-Mo compositions. Annealing for 250 hours at 1600 F produced a precipitate in the matrix phase and increased hardness in some of the tungsten-base alloys under study. Oxidation tests at temperatures up to 2000 F showed that additions of Al, Cr, Mo, Pd, and Ti improved the oxidation resistance of the W-Ni-Fe base. A fused coating of AMS 4775 protected a 90W-6Ni-4Fe alloy for 72 hours in air at 2100 F."
