ABSTRACT:
A consolidated tungsten alloy body consisting essentially of from about 60% to about 98% by weight of tungsten, balance, nickel and iron, containing a continuous phase of tungsten and a discontinuous phase of grains of a tungsten, nickel and iron alloy having an aspect ratio of at least 4:1 relatively uniformly distributed throughout the continuous phase and wherein said body has a recrystallization temperature of from about 1000.degree. C. to about 1200.degree. C. A process for producing the consolidated bodies comprises working and annealing at controlled temperatures to achieve the desired properties. The working temperatures are from about 700.degree. C. to about 900.degree. C. and the annealing temperature is preferably 1200.degree. C.
