  • Manufacturing process and apparatus
    Patent number: 7763204
    Abstract: A manufacturing process that comprises placing an article within a particulate medium (4), the article being provided with a molded body (8) of small ceramic particles. On application of heat and pressure the small ceramic particles are pushed between the particulate medium (4) to permit localized deformation of the article (2).
    Type: Grant
    Filed: September 12, 2008
    Date of Patent: July 27, 2010
    Assignee: Rolls-Royce plc
    Inventors: Wayne E. Voice, Nicholas Wain
  • Manufacture of an article by hot isostatic pressing
    Publication number: 20100158742
    Abstract: In a hot isostatic pressing (HIP) process, for example for securing blades (5) to a disc (3) to form a blisk (1), the temperature of the powder (6) to be consolidated is raised to a predetermined temperature, which may be the eventual required pressing temperature, before the pressure rise to the pressing pressure is initiated. If the powder is a titanium alloy and the process employs steel tooling pieces, the application of pressure occurs only when the temperature has risen to the extent that the steel is harder than the titanium alloy.
