Title: Improvements in and relating to fabricating methods for high strength alloys
IPC: C22F1/00
Filed: 1968-12-23
Abstract: 1,253,861. Working at specified temperatures; making blades, discs and vanes; forging. UNITED AIRCRAFT CORP. 23 Dec., 1968 [22 Dec., 1967], No. 61190/68. Headings B3A, B3H and B3V. A high strength alloy, e.g. Ni or Ti alloy, is fabricated by compression warm working it below but within 450‹ F, of its recrystallization temperature to produce at least a 4 to 1 reduction in cross-sectional area, then forging the alloy between 1400‹ F. and its recrystallization temperature and finally heat-treating it to regain the high strength properties. The alloy is compression worked by rolling, forging or extrusion in one or more stages and is then forged in an inert atmosphere using Mo or Ni alloy dies heated by induction coils. Vanes, blades and discs for a gas-turbine engine may be made by the method. In an example, a Ti-8% Al-1% Mo-1% V alloy is first reduced at 1300-1700‹ F. and forged at 1700‹ F. at a strain rate of 0À5 inch<SP>2</SP>/min. The alloy is thereafter solution heat-treated to produce grain growth and precipitation hardened to restore the high strength properties.

Abstract: 1,256,159. Pressing fabrics. KANEGAFUCHI BOSEKI K.K. 22 Dec., 1969 [29 Dec., 1968], No. 62217/69. Heading D1S. The pressing plates 1 of a flat press for fabric are each maintained at a substantially constant temperature below 100C by supplying steam into a through-conduit 2, maintaining the pressure in the conduit 2 at a predetermined pressure below atmospheric pressure, and discharging the condensate produced in the conduit 2 while decreasing pressure outside the outlet of the conduit so that the pressure outside this outlet is always lower than the pressure within the conduit. Steam is supplied to the conduit 2 through a pipe 3 and a valve 5 and leaves through a conduit 14 connected to a steam trap 7 through a valve 6 and to a pump 10 through a valve 8 and a pressure gauge 9. The pressure in the conduit 2 is indicated by a gauge 4. The steam trap 7 may be bypassed by a conduit 11 having a valve 12. In operation, initially, valves 5, 6 are closed and the valve 12 is opened. The pump 10 is driven so that air pressure in the conduit 2 is decreased to a predetermined value. The valve 12 is closed and the valve 5 opened to supply steam to the conduit 2 whilst the pump 10 is continuously driven and the valves 6, 8 are open. To ensure that the steam which has condensed in the conduit 2 is discharged through the steam trap 7, the pressure in the conduit 2 is maintained at a higher pressure than that in the conduit 14 by at least 0.1 kg./cm.<SP>2</SP>, preferably 0.3 kg./cm.<SP>2</SP>. The condensate is discharged from an outlet 15 and air or steam is discharged from an outlet 13.

Title: Alumina, calcia and baria sealing composition
IPC: C03C3/12
Filed: 1980-02-13
Abstract: An improved sealing composition for use between alumina ceramic parts, or between alumina ceramic and refractory metal, consists of 35-55% Al2O3, 32-42% CaO, 13-19% BaO and up to 1% MgO. Up to 3% B2O3 may be added for improved wetting and flow characteristics. The composition has a lower liquidus temperature (1325 DEG C) than an otherwise similar one previously used which included 5% MgO, and its thermal expansion coefficient is less affected by dissolved Al2O3. As a result, a closer thermal match with alumina ceramic can be maintained during seal processing and the rejection rate is reduced.
