Abstract

1,022,027. Solid state welding, making turbine blades. ROLLS-ROYCE Ltd. Nov. 11, 1963 [Nov. 28, 1962], No. 45075/62. Headings B3A and B3R. Metal parts are joined by forming corresponding surfaces on the parts, mating the surfaces together heating the parts at between S-¢‹ C. and S-15‹ C. (where S is the solidus temperature of the metal parts or is the lower of the two solidus temperatures where the parts are of different metals) without the application of external pressure so that the parts are joined by solid state diffusion bonding. In making turbine blades with internal cooling passages, the blades are formed of two or more parts having slots at the desired location of the passages and the parts are diffusion bonded. The parts may be cast, forged, machined or electroformed or made from sintered compacts. Mating surfaces are ground on the parts. The parts are heated for 2-24 hours in a vacuum furnace at a pressure of less than 5 x 10<SP>-5</SP>% or to a temperature between 0À5‹ C. and 15‹ C. below the solidus temperature of the parts which may subsequently be shaped, forged, coined or machined. The parts which may be of nickel base alloy are preferably heat treated at 5-20‹ C. below the solidus temperature for 15-60 minutes in a vacuum furnace prior to jointing.
