Creep-resistant aeroengine shaft steels: precipitates and consequences

Zixin Huang

Abstract

Creep resistant steels must be stable over long periods of time under severe operating condi- tions. This paper reviews precipitation in Cr–Mo steels and maraging steels destined for elevated temperature applications. It also covers aspects of structural evolution, strengthening and degra- dation, all of which are essential for alloy design. Two classes of steels are emphasised, those with origins in the power generation industries, and a novel approach based on intermetallic precipitates.
