Abstract
A series of superalloy compositions are described, which when processed according to a described processing sequence, produce homogeneous superalloy articles which contain an exceptionally high amount of the gamma prime phase. These alloys contain large amounts of aluminum and chromium and hence are quite oxidation resistant. The processing sequence includes rapid solidification to suppress the formation of the low melting eutectic phases which would otherwise occur.
