APPLICATION OF THERMAL-CYCLIC PROCESSING FOR INTENSIFICATION OF NICKEL ALLOYS DETERIORATION

Abstract

The possibility of intensification of the nickel alloys \ EI437B, E1617, E l86 deterioration at thermal heat cycling is considered in the article. The changing of the alloys hardness at heat-cycling treatment in intervals of the temperatures of chilling and deterioration is investigated. It is shown that application of heat cycling allows to increase the hardness and resistance at high temperatures as compared to standard treatment.
