ABSTRACT:
A high strength nickel base superalloy having a novel microstructure is described. The article consists of a gamma matrix containing a oriented gamma prime second phase having a plate or rod form. This noncuboidal gamma prime phase is produced by aging solution treated material under an applied stress. When this process is applied to a certain class of superalloys which are rich in refractory elements, the resultant structure provides exceptional resistance to creep at elevated temperatures.
