The Effect of Sulfur and Phosphorus Impurities on the Long-Term Strength of Single Crystals of the ZhS36-VI Alloy under Testing on the Basis of up to 1000 Hours

Abstract—The effect of elevated sulfur and phosphorus on the long-term strength of single crystals of the ZhS36-VI alloy during testing on the basis of 40, 500, and 1000 h was studied. It was established that, when tested on a short basis, these impurities do not adversely affect the properties. When tested on the basis of 500 h, the properties of an alloy with a high content of sulfur and phosphorus are reduced, but when tested on a basis of 1000 h, the properties of an alloy with a high content of sulfur are reduced to the level of a metal with a low sulfur content. A mechanism is proposed for restoring the long-term strength of the alloy during long-term test bases.
