Power Plant Steels: Remanent Life Assessment and the Approach to Equilibrium

The steels used in the power generation industry are almost always given a severe tempering heat treatment before they enter service. This would, in most circumstances, give them a highly stable microstructure which is close to equilibrium. In fact, they undergo many changes over long periods of time. This paper is a review of some of the methods which exploit the changes in order to estimate the life that remains in alloys which are only partly exhausted.
