Title: DEVELOPMENT AND EVALUATION OF HIGH-TEMPERATURE TUNGSTEN ALLOYS. Quarterly Report No. 2, January 1, 1960-March 31, 1960

Abstract

S>Room -temperature properties were determined for WNi --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 deg 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 deg 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 deg F. (auth)
