Manufacturing Process for the Production of Near Net Superalloy Disk Shapes by Isothermal Forging.

The objectives of this manufacturing technology program are 1 to reduce the cost of manufacturing IN-100 disks, seals, and spacers for the F100 engine by forging closer to finish shape thereby reducing input material and machining costs 2 to establish a reproducible manufacturing process for the production of near net disk, seal, and spacer shapes by advanced isothermal forging techniques 3 to demonstrate the developed process and fully laboratory qualify the forgings 4 to extend established nondestructive inspection techniques as required to assure full inspection of near net disk, seal, and spacer shapes.
