Abstract

Guidelines are provided on some aspects of material behaviour and plant operation, which allow designers and operators of high temperature plant to estimate lifetimes of components where the useful service lifetime is determined by the integrity of protective oxide scale. The methodology follows a simple checklist with guidance on where more detailed investigation may be necessary. The methodology is supported by detailed case studies that illustrate several different failure mechanisms. The main case study addresses the issue of scale spallation during a single cooling cycle for two alloys -one forming a chromia scale and the other fomling an alumina scale.
