摘要
Creep resistant steels must be stable over long periods of time under severe operating conditions. 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 degradation, 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.
