The Influence of Sulfur, Phosphorus, and Silicon Impurities on Structure and Properties of Single Crystals of Nickel Heat-Resistant Alloys

Resumo

Structural modifications in single crystals of nickel heat-resistant alloys with increased content of sulfur, phosphorous, and silicon are described. A negative influence of these impurities on long-term and fatigue strength at operating temperatures has been demonstrated using large test bases.
