Course content

The course gives a deep insight into the microstructure and application properties of steels in general, and especially of steels used in offshore industry. The course focuses on the relationships between phase diagram, chemical composition, processing, microstructure, and mechanical -, corrosion - and welding properties. Important topics are strengthening mechanisms, effects of alloying elements, formation of martensite, the bainite reaction, acicular ferrite, heat treatment of steels (including hardenability), tempering of martensite, thermomechanical treatment, embrittlement and fracture, stainless steels, and weld microstructures. Corrosion of steels.

Learning outcome

After completion of the course the student should be able to - Describe the microstructure and application properties (including mechanical, corrosion and welding properties) of steels used in offshore industry, as well as explaining the effects of alloying elements. - Explain the fundamental relationships between chemical composition, phase diagram, processing, microstructure, and application properties of offshore steels. - Consider whether a microstructure is favourable, and from the microstructure consider whether the alloy has got an optimum processing (cooling, heat treatment, etc.). - Discuss correct choice of alloy and processing (including welding) for offshore applications. - Carry out simple calculations connected to microstructure and mechanical properties. - Discuss selected corrosion mechanisms relevant in offshore applications.

Learning methods and activities

Lectures and exercises in gropus. If the teaching is given in English the examination papers will be given in English only. Students are free to choose Norwegian or English for written assessments. Work load ca. 200 hours during the semester.

Compulsory assignments
