摘要：
Volume fractions of the gamma phase are calculated in the form of various geometrical figures depending on the ratio of the volume fraction of the gamma and gamma' phases. The gamma phase in the form of plates prevails at a 70% content of the gamma' phase, which is the most characteristic of the VZhM4 alloy after the complete heat treatment. The qualitative analysis is carried out for the arrangement of satellites in the reciprocal space of the VZhM4 single-crystal Ni-based superalloy. The lattice of the reciprocal space with the satellites caused by the stress state of gamma phase interlayers is constructed in the form of various geometrical figures. The set of experimental sections of the 3D structure of (222), (313), and (202) reciprocal lattice sites is obtained.
