Phases stable, karbidverstaerkte nickel - super alloy eutectics with improved strength with respect to rule at a high temperature and improved resistance with respect to the formation of carbides by a helicoidal guide

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.
