Diffusion-controlled thermal aging of 15X2HM[Phi]A structural steel

At nuclear power plants, metal equipment is subjected to temperatures of 290-320°C. That may lead to thermal aging and reduce the resistance to brittle failure. The degradation of the steel's properties may be taken into account in terms of the shift in the critical brittleness temperature. The...

Description
Summary:At nuclear power plants, metal equipment is subjected to temperatures of 290-320°C. That may lead to thermal aging and reduce the resistance to brittle failure. The degradation of the steel's properties may be taken into account in terms of the shift in the critical brittleness temperature. The thermal aging of steel is controlled by the diffusion of carbon and associated with carbide deposition. The results permit prediction of the properties of steel and the shift in the critical brittleness temperature corresponding to a life of 60 years.[PUBLICATION ABSTRACT]
