Abstract
A method for determining the level of interfacial stresses in single-crystal nickel superalloys and the results of its determination are presented. The splitting of the (h00) X-ray diffraction peaks in the X-ray diffraction patterns of the γ and γ′ phases that is caused by interfacial thermal stresses is studied.
