27-727 Mechanical Behavior in Extreme Enviroments
6 units, Carnegie Mellon University
The purpose of this course is to discuss the mechanical behavior of materials used in extreme environments in the production and distribution of energy. The focus will be on the production and refining of oil, conventional power plants and nuclear power plants. The course will begin with a discussion of the materials used in these applications and this discussion will focus on compositions, heat treatment, microstructure and nominal mechanical properties after heat treatment. The materials will include low alloy steels, stainless steels, nickel base alloys and zirconium alloys used as fuel cladding in nuclear reactors. The mechanical behavior discussed will be the behavior of materials at high temperatures, various types of stress corrosion cracking and the toughness of steels used at low temperatures. In addition, various forms of embrittlement associated with long service times at elevated temperatures will be discussed. These will include hydrogen attack, temper embrittlement due to segregation of impurities and alloying elements, the formation of phases which result in embrittlement and embrittlement due to irradiation in nuclear reactors. Many of these materials are expected to be in service for many years so, where time permits, methodologies used to predict mechanical properties after long times in service will be discussed.
