Abstract

The features of the production of single-crystal blades from nickel heat-resistant alloys are considered. Metallographic and fractographic studies of the destroyed blades were performed to identify the causes of destruction. The features of fatigue and static destruction of single-crystal turbine blades have been studied by optical and scanning electron microscopy using X-ray spectral microanalysis. Recommendations are given to prevent the formation of recrystallized polyhedral grains.
