REALIZATION OF THE POTENTIAL CAPABILITIES OF AN INTERMETALLIC ALLOY BASED ON THE NI3AL COMPOUND, INCLUDED IN ITS DEVELOPMENT

Studies of structural and phase transformations in a cast structural alloy based on the Ni3Al compound depending on the alloying balance, heat treatment, use of a heat-resistant coating, and performance of high-temperature static tests are presented. It is shown that the intermetallic alloy VIN4M and the composite coating calculated taking into account the alloying balance retain thermal stability after heat treatment including hot isostatic pressing and after long-term static tests.
