© 2020, Pleiades Publishing, Ltd.Abstract: The formation of anomalous particles (granules) with a significantly different content of microalloying interstitial elements of carbon and boron characterizes the heterogeneity of the composition of rapidly quenched particles of high temperature Ni-based superalloys and stainless steels powders manufactured by the plasma rotating electrode process (PREP) technique. A detailed multiscale experimental study of the microstructure of PREP powders and PM HIP compacts of Ni-based superalloys and stainless steels is carried out in order to reveal the features of the microstructure of anomalous granules in the as-received state and consolidated state. Direct nuclear methods of activation autoradiography on carbon, track autoradiography on boron, metallography, SEM, EDX, and OIM are used. A significant effect of carbon and boron on the dendritic segregation of carbide-forming and boride-forming alloying elements in anomalous granules is revealed. The features of the behavior of carbon and boron, which determine the formation of the microstructure of anomalous granules and their retention in PM HIP compacts, are established.
