Abstract

The density of alloy ZhS6U in cast state is studied after testing for long-term strength, hot isostatic pressing, thermal vacuum treatment, and long-term operation. The density of the alloy is determined using the method of hydrostatic weighing of test specimens and specimens cut from turbine blades.
