Application of New Concepts to the Design of an Advanced Nickel-Base Superalloy - Udimet 710 690103

Sulfidation attack of nickel-base superalloys operating in salt air environments has received major technical attention in recent years due to the rapid and catastrophic nature of such attack. Also, structural stability of nickel-base alloys subjected to long exposures at elevated temperatures has received considerable technical interest because of the often associated property degradation with structural changes, and the need to produce reliable material behavior over longer periods of time.
This paper briefly reviews the technology of sulfidation attack and structural stability and discusses the application of knowledge gained to the design of a new nickel-base superalloy, Udimet 710.
