Metallographic Characterization of Rene 95 Forgings.
Abstract
Rene 95 is a high strength nickel-base super-alloy with a 1200F temperature capability primarily used for compressor and turbine disk applications. In addition to the conventional precipitation and solid solution strengthening mechanisms, Rene 95 is further strengthened through the incorporation of of thermomechanical processing (TMP). This results in the formation of a duplex structure consisting of warm worked grains surrounded by a 'necklace' of very fine recrystallized grains thus resulting in superior tensile and stress-rupture properties. The microstructure consists of gamma prime precipitates distributed through the gamma matrix with carbides of the MC type occurring predominantly throughout the necklace regions. A detailed discussion of the morphologies of these phases is presented in the report. (Author)
