THE STUDY OF FOUNDRY TECHNOLOGICAL AND STRENGTH CHARACTERISTICS OF THE CAST VERSION OF ALLOY ВЖ159, IN RELATION TO THE MANUFACTURE OF SHAPED CASTINGS OF PARTS OF AIRCRAFT GAS TURBINE ENGINES
The results of studies of the technological properties of foundry and the basic strength characteristics of the cast version of alloy ВЖ159, superior in the properties of heat-resistant alloy of Nickel-chrome based ЭП648. ВЖ159 alloy has high weldability characteristics, including, in hardened condition, which ensures maintainability of parts and welded parts of it. It is concluded that the use of alloy ВЖ159 possible for the manufacture of shaped castings of parts of aircraft engines.
