Abstract

A study of the structure of a single-crystal sample of a nickel heat-resistant alloy, brittle destroyed by mechanical cutting. The study was carried out using x-ray diffractometry – «swing» and the Laue method. The possibilities of the Laue method for studying local defects of various origin are shown. Based on the obtained data, an assumption is made about the recrystallization nature of structural defects in a single crystal of a nickel heat-resistant alloy; the elastic properties of the single crystal are estimated.
