摘要：

The unconstrained lattice parameters and volume fractions of gamma' for a low misfit nickel based superalloy were evaluated using X-ray diffraction techniques. Extraction techniques were used to provide unconstrained gamma' powders for both water quenched and slow cooled samples that were aged at 760 degrees C for 0, 25, 50, 100, and 200 h. The external standard method was used to determine the volume fraction for the unaged water quenched sample and the slow cooled sample aged for 200 h. These two extremes in processing conditions provided an increase in the total volume fraction of gamma'. Published by Elsevier B.V.
