Understanding the HIP (Hot Isostatic Pressing) Consolidation of P/M Nickel-Base Superalloys.

Abstract

Superalloy powders have been completely characterized. The different size distributions of powders have been containerized and are ready for HIP at the commercial condition of pressure and temperature, which is 15 ksi at 2050 degrees F. All creep specimens are machined and creep tests are now under way (two creep runs have already been completed). Framework for the new HIP model has been developed in order to include unequal particle sizes. Keywords: Hot Isostatic Pressing; Alloy Powders; Consolidation.
