High Temperature Alloys Overview

Abstract

A new single-crystal nickel-based superalloy has been developed as part of the GE Aviation strategy of “Rhenium Reduction” This new material provides second-generation properties while using significantly less rhenium. The new alloy development and introduction is part of the four-part strategy of “revert, recycle, recover, and reduce.”
