Bainitic steels and alloys for power plants

M.J. Peet,    University of Cambridge, UK

Abstract:

This chapter concerns bainitic steels for power plants based on low-carbon, low-alloy steels. The various transformations in steel – particularly bainitic transformations – are explained beginning with elementary principles. Power plant steels are usually used in a severely tempered condition. The structure approaches equilibrium on tempering and in service with a corresponding reduction in the driving force for further transformation. The effect of tempering upon mechanical properties has been represented by combining the Ashby–Orowan and Hall–Petch equations. The effect of composition on the tempering process is outlined. Examination of desirable ...
