Title: Improvements in or relating to alloy compositions
IPC: C22C1/05
Filed: 1934-12-24
Abstract: A metallic composition for use in making tools, dies, sand-blast nozzles, contact points, well-borers, and other articles is made by alloying one or more refractory carbide-forming metals, such as tungsten, tantalum, titanium, zirconium, molybdenum, chromium, thorium, and rhenium, with one or more metals of lower melting-point, such as iron, manganese, nickel, cobalt, silver, and copper, and carburizing or carburizing and boronizing the product.  A preferred composition is a carburized or carburized and boronized alloy of tungsten and one or more iron-group metals.  The product may be finely powdered and used as an abrasive or compacted into solid bodies.  In making a compact body, the powdered alloy may be mixed with base metal oxides, reduced in hydrogen, pressed to the required shape, baked, and heated to over 1400 DEG  C. but below the melting point of the base metal.  In making the alloys, compounds such as cobalt oxide, iron oxide, and thorium nitrate, or cobalt tungstate, iron tungstate, and tungsten oxide may be used, the mixed powders being reduced in hydrogen.  The carburizing may be effected by mixing the alloy powders with lamp black and heating to about 950 DEG  C. in hydrogen, crushing and milling the product and reheating to about 1250 DEG  C. in a carbonaceous, hydrogen, or reducing atmosphere.  If boronizing is to be effected, boron suboxide or boron nitride is used along with the lamp black.  The final product may contain 57,5-92,5 per cent of refractory metals, 0,25-5 per cent of iron, 0,25-2,5 per cent of chromium and thorium, 5-10 per cent of carbon and boron, and 2-25 per cent of cobalt and nickel.
