X-Ray Topography Study of the Nickel Superalloy CMSX-4 Single Crystals

Article Preview

The paper attempts to determine structural perfection of monocrystalline nickel superalloys using X-ray topography. Monocrystalline bars and turbine blades were manufactured in an ALD Vacuum Technologies furnace using the Bridgman method. Pulling out rates typical for CMSX-4 nickel superalloys were used. It has been found that in the case of monocrystalline bars the structural perfection determined based on X-ray topograms does not depend on the distance from the selector. Instead, for blades the structural perfection significantly decreases with increasing distance from the selector.
