Development of SLZhS32 BR economically doped heat-resistant alloy with single-crystal structure

A study of the structure of a single-crystal sample of a nickel heat-resistant alloy, brittle destroyed by mechanical cutting. The study was carried out using x-ray diffractometry – «swing» and the Laue method. The possibilities of the Laue method for studying local defects of various origin are shown. Based on the obtained data, an assumption is made about the recrystallization nature of structural defects in a single crystal of a nickel heat-resistant alloy; the elastic properties of the single crystal are estimated.

A comparative study of structural features of the blade castings having a single-crystal structure and made of heat-resistant carbon-free and carbon-containing high-temperature nickel alloys upon directional crystallization with 001 crystallographic orientation is carried out. The results of the effect of directional crystallization modes on the formation of the structure and defects of castings of working blades made of carbon-containing and carbon-free high-temperature nickel alloys are presented. Changes in the degree of pickling of the near-surface layer of casting are presented as a function of pickling conditions. The microstructure of the near-surface zone of castings made of ZhS32 heat-resistant alloy is studied after different modes of their technological processing. It is shown that blade castings with a single-crystal structure made of heat-resistant carbon-free superalloys have a tendency to formation of the block structure and appearance of surface recrystallized grains. Recommendations on the use of methods of nondestructive X-ray control of blades made of carbon-frees alloys and precautions regarding birth of microporosity on the shelf and in the blade lock are specified.
