Properties and Microstructure of Allvac 718Plus Alloy Rolled Sheet

Abstract

Design and construction of advanced aerospace systems capable of meeting demands of accessto-space, operations in and through space, and high speed/hypersonic flight are constrained by material challenges. Requirements for airplane-like operations of reusable systems fall most heavily on the needs for improved thermal protection systems and durable, lightweight structures. Robust and affordable industrial manufacturing procedures for these material systems frequently do not exist, even for materials such as some nickel-based superalloys, which have attractive high-temperature performance, manufacturability, cost and durability.
