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.
