Description

Highlights: ► Age hardening behavior of AEREX™ 350 superalloy was investigated. ► The microstructure is sensitive to the solution and the aging treatments. ► The microstructure of the alloy can be optimized for different applications. - Abstract: Age hardening behavior of selected samples of AEREX™ 350, a nickel-cobalt based superalloy, was investigated in this article. The relationship between the microstructure and mechanical properties was elucidated using hardness and compression testing methods and optical, scanning and transmission electron microscopy techniques. It was found that the microstructure is sensitive to the temperature of the solution and the aging treatments. This approach may be used to optimize the microstructure of the alloy for different applications.
