The mechanical properties of nickel-base superalloys used in disk and blade materials for gas turbine engines can be maximized by controlling their microstructure, such as the size of precipitates. In this study, we investigated the size of gamma prime precipitates after age hardening heat treatment at 650-980 oC for 1-48..... More
