Title:
A QUASI-ISOTHERMAL FORGING METHOD OF A DISK SHAPED FORGING OF NICKEL-BASE SUPERALLOYS IN AIR
Document Type and Number:
WIPO Patent Application WO/2008/106858
Kind Code:
A1
Abstract:
A quasi-isothermal forging method of a disk shaped forging of nickel-base superalloys in air includes heating and preprocessing an initial alloy bar thereby obtaining a fine crystal ring blank, heating the ring blank to a temperature of 995-1005? and heating an upper die and a lower die to a temperature of 950-965?, insulating the ring blank, the upper die and the lower die, positioning the heated ring blank between the upper die and the lower die, and applying a force on the ring blank by the upper and lower dies, thereby forming a disk shaped forging in air.
