Abstract
IN an article in NATURE of March 201, Dr. C. J. Smithells describes a very interesting method of producing alloys of tungsten without melting the tungsten itself. He mixes tungsten powder together with copper and nickel powder and then heats them to 1,450° C., at which temperature the mixture sinters, the tungsten becoming embedded in a tungsten-copper-nickel eutectic. He thus avoids the technically extremely difficult, if not impossible, task of heating large masses of tungsten to melting point.
