Abstract
500,114. Alloys. BOLTON, C. A. July 27, 1937, No. 20791. Convention date, Oct. 10, 1936. [Class 82 (i)] Alloys comprising carbides, borides, nitrides and silicides of titanium, zirconium, thorium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, uranium, and boron are made by heating a mixture of materials serving to form the desired compound and one or more additional materials such as molybdenum, tantalum, nickel, or cobalt until shrinkage of the mass is complete or shortly thereafter, powdering the product, and compressing and sintering the powder. Both in the first heat treatment and in the sintering operation the temperature is raised rapidly to the point at which shrinkage commences, whereafter it is maintained constant until shrinkage is complete or shortly thereafter. In some cases the additional material may comprise up to 2 per cent of a metal such as iron, nickel, or cobalt which forms mixed crystals with another of the metals present. A specific example consists of 75 per cent of tungsten carbide, 10 per cent of molybdenum, 8 per cent of vanadium, 2 per cent of nickel, and 5 per cent of silicon.
