Abstract

1,153,932. Sintered alloy foil; alloys. TEXAS INSTRUMENTS Inc. Sept. 28, 1966 [Oct. 13, 1965], No. 43384/66. Headings C7A and C7D. In a process of forming a sintered alloy foil e.g. 0À001''-0À008'' thick a supporting carrier such as stainless steel strip is coated with a slurry of the powder constituents of the alloy and a binder which is dried and squeezed to bond the particles, the coating is removed from the carrier, presintered, squeezed as by rolling and finally sintered. The following alloys are specified as examples: 71% Ni - 10% Si - 19% Cr; 92% Ni - 4À5%Si-3À5%B; 80/90% Fe - 10/20% Al; 90% Cu - 10% Ti; 70/75% Ni - 25/30% Ti. The binder used is a long chain high molecular weight organic compound such as methyl cellulose, cellulose ether, polyethylene oxide, polyvinyl pyrallidone with water as a carrier. The powder constituents of the alloy should have a particle size less than 100h, mainly 50 h. and the slurry formed should contain 50 - 75% solids with a viscosity of 1000-4000 c.p.s. As shown in Figure 1 the slurry 9 is coated on a stainless steel strip 1 by rollers 19, 21 to form a wet coating 0À010" thick. The coating is dried by resistance heating of the strip 1 via 33, 8 and 10 and the dried coating is rolled by rollers 39, 41 to a 10-50% reduction. The coatings 34, 36 formed on both faces of the strip 1 are removed and presintered in argon or hydrogen in furnaces 43 and 45 respectively, the temperature being insufficient for homogenization of the alloy. The presintered strips are rolled at 47/49, 51/53 respectively to a 5-40% reduction and finally sintered at 55 and 57 respectively. The process is of particular value for brittle alloys since the rolling is carried out on the presintered strip i.e. before alloying has occurred to form the brittle alloy.
