Summary

The course deals with modern structural materials which are used in conventional power plants: thermal power plants and heating plants, gas power plants, nuclear power plants. Students will learn about their chemical composition, heat treatment procedures, structure, properties and consequences of degradation processes taking place under conditions of their practical exploitation in various conventional energy sources. Results of evaluation of service failures of structural components are demonstrated on case studies.
