Abstract: Methods for increasing the forgeability of cast superalloy materials are described. An extremely overaged microstructure is developed by solutionizing the material and slow cooling in the vicinity of the solvus temperature to cause a precipitation of extremely coarse gamma prime material. Subsequently the material can be isothermally forged.

Abstract: A composite flame spray powder comprising powder particles having as components, cast iron, molybdenum (as such and/or as ferromolybdenum), and boron (as such and/or as ferroboron), unalloyed together. The composite particles are preferably in a form having a cast iron core, of a size between -170 mesh standard screen size and +15 microns, with particles of molybdenum and boron of a size between about -20 and +0.1 microns, bound to the surface of the cast iron core with a binder, the molybdenum being present in amounts of about 20% by weight and the boron in amounts of about 1% by weight based on the total of the cast iron and molybdenum. When flame sprayed, the composite particles produce a coating having high wear and scuff resistance characteristics and low friction.
