You could have some idea using joined book from EPRI :

« Fossil Plant High-Energy Piping Damage:  Theory and Practice Volume 1: Piping Fundamentals »

 You can also find articles by googling on Internet.

See for instance following link to an article available on RG :

https://www.researchgate.net/publication/286858660_Microstructural_degradation_in_boiler_steels_Materials_developments_properties_and_assessment

The problem with books is that long time experience and photographs have to be collected to build up the kind of book you are interested in. Getting collections of metallographies on low-alloy Cr-Mo steels like the two you cite (1Cr0.5Mo – 2.25Cr1Mo) require much expert work in power plants and agreement of power plant users : so protect know-how and secrecy are master words. One usually has to pay a lot to get access to such information ….. when access is given ! Just follow the link to have an idea :

I enclose an additional document from the ECSC (Europe) on life assessment and creep analysis. It is old (1985) but full of information which is still relevant. You can certainly refer to it. The figures are rather poor (see e.g. Fig 43, Fig. 49) but the descriptions of microstructural damage and the graphics giving a.o. the influence of cavitation and other parameters on the residual life are rather good and interesting (to be used in connection with metllographical results). Please note that 1Cr-0.5Mo- and 2.25Cr-1Mo-steels are also called 13CrMo44 and 10CrMo910 respectively (German) or Chromesco I and Chromesco III (respectively).

Hi Mr. T.P. Ismail,

In addition to the valuable reference books suggested by the experts, I found following two works to be lucid and helpful:

1. Toft, L.H. and Marsden, R.A. (1961). The structure and properties of 1%Cr – 0.5%Mo steel after service in CEGB power stations”, in Structural Processes in Creep, ISI Special Report 70, Iron and Steel Institute, London, pp. 276-294.

2. VGB-TW 507 – "Guideline for the Assessment of Microstructure and Damage Development of Creep Exposed Materials for Pipes and Bioler Components“, VGB Technical Association of Large Power Plant Operators, 1992.

You may also go through

Furtado, H.C. and Le May, I. (1996). Metallography in Life Assessment of Power Plants. Materials Characterization, Vo.36, pp175-184.

Some of the subtle differences in microstructure through replica technique has been well explained and attributed to the actual conditions in the boiler.

Thank you. Hope it helps.
