superleghe stable eutectic phase nickel base, reinforced with carbides.having improved resistance to tension failure at high temperatures and improved resistance to the formation of carbide surface.

摘要

Monocarbide reinforced nickel-base eutectic superalloys which are substantially phase stable and have improved high temperature stress-rupture strength with improved resistance to the formation of surface nucleated carbides are provided. These superalloys are especially suited for making unidirectionally solidified anisotropic metallic bodies in the form of vanes and rotating blades for aircraft gas turbine engines.
