  • Nickel base alloy forged parts
    Patent number: 5360496
    Abstract: Disclosed is a large alloy forging and method for making it. The forging having an alloy composition selected from one of a nickel base alloy, a cobalt-chromium-nickel base alloy, a nickel-cobalt base alloy and an iron-nickel-chromium-molybdenum alloy and having a grain size of ASTM grain size 4 or finer, as measured by ASTM method E112 and having a tensile strength in the range of 135 to 175 KSI. The process includes: (1) four upset forgings, (2) a rapid cooling after the final upset cooling, (3) a first and second upset forging with a reduction greater than 50%, (4) a third upset forging with a reduction greater than 25.%, and (5) a forging process with a fourth upset forging with a reduction greater than 50%.
