Abstract

The article analyzes the methods of x-ray diffraction used to assess the quality of the structure of single-crystal castings of heat-resistant nickel alloys. The results of determination of crystallographic orientation of single crystals of nickel heat-resistant alloys obtained on an x-ray diffractometer equipped with a curved position-sensitive detector are presented. The data of optimal shooting conditions for obtaining a «swing» curve in order to control the crystallographic orientation of single-crystal castings are presented.
