© 2021, Pleiades Publishing, Ltd.Abstract: Occurrence of anomalous particles (granules) with significantly different concentrations of microalloying interstitial elements of carbon and boron is an important characteristic of composition homogeneity of rapidly quenched powders of high temperature Ni-based superalloys and stainless steels produced by the PREP method. Detailed multiscale experimental study of behavior of boron and carbon in PM HIP compacts of Ni-based superalloys under hot deformation and heat treatment has been performed. Direct nuclear methods of activation autoradiograph on carbony by the reaction 12C(d,n)13N and track autoradiograph on borony by the reaction 10B(n,α)7Li, metallography, SEM, EDX, and OIM have been used to reveal features of microstructure evolution of anomalous granules in PM HIP compacts of high temperature Ni-based superalloys. Significant influence of hot deformation and heat treatment on behavior of boron and carbon in PM HIP compacts of high temperature Ni-based superalloys has been detected. Significant differences in evolution of carbon and boron have been detected and discussed. A schematic TTT diagram is proposed for precipitation of the boride phase in comparison with precipitation of the carbide and γ' phases.
