Microstructural evolution in Grade 91(9CR-1MoVNb) power plant steels
thesis
posted on 2014-08-20, 14:40 authored by J.J. Sanchez-HantonThe aim of this research project was to gam a complete, quantified, understanding of
microstructural changes in high Cr ferritic-martensitic power plant steels, as a function of preservice
heat treatment, stress, time and temperature. The creep strength, which is the main
design criteria for this class of alloys, depends on the stability of the microstructure, which
consists of tempered martensite and a fine dispersion of carbide precipitates. An
understanding of the changes of these two features forms an essential process towards the
creation of a physically or microstructural-based model, which may improve the current
approaches towards the prediction of remanent operational lifetime of these materials in
service in conventional fossil-fired power plant... cont'd.
