Abstract

In this article the substructure of cast Ni-based superalloys and application of stress condition model of structural components are described. The inapplicability of standard technique of x-ray tensometry «sin2ψ method» was shown for single-crystal and direc-tionally solidified samples of superalloys. A structural model of superalloy and the technique of calculation of interphase tension in single-crystal Ni-based superalloys are offered. This structural model is working with х-ray diffraction analysis and experimental data on the crystal lattice misfit (i.e. mismatch of γ- and γ'-phases crystal lattice con-stants).
