Strain/Oxidation Interactions in Steels and Model Alloys

摘要

AbstractStrain/oxidation interactions in steels and model alloys The strains generated in oxide films on a number of materials of interest to the power generation industry are considered in relation to their operating conditions. Topics discussed the growth of nuclear canning alloys, oxide spalling, the formation of multilayer oxides during internal boiler corrosion and low ductility failures in austenitic stainless steels. The strains induced during thermal cycling are considered in detail and the temperature changes required to cause film craking are estimated and compared with observed spalling behaviour.
