Course content

This course is a continuation of TMM4100 - Materials Technology, providing a deeper exploration of key aspects of materials technology applied to mechanical engineering. It focuses on the intricate relationship between the structure, properties and performance of materials aligned with engineering applications and addresses solutions to various material degradation challenges.

With the aim at providing both fundamental and applied knowledge on materials technology, the course focuses on metallic materials, materials degradation processes such as wear, hydrogen embrittlement and corrosion, with a particular emphasis on their relevance to their industrial applications. Other materials than metals will be also introduced. The course begins with the structure and mechanical properties of metals, followed by the topics including the deformation mechanisms (both elastic and plastic), strengthening mechanisms, fatigue and fracture behavior of metals, and mechanical testing at various length scales.

The course provides a thorough knowledge of some materials degradation processes and the corresponding mitigating actions, such as, but not limited to, wear, lubrication, hydrogen embrittlement, and corrosion. Theoretical and applied knowledge on those degradation processes, such as the basic mechanisms of corrosion and wear, protection methods and degradation management strategies will be provided in this course.

The topics covered in the course are directly aligned with the needs of industrial applications. The knowledge gained in the course will enhance students’ understanding of the materials mechanical behavior and degradation mechanisms in various industrial sectors such as energy and manufacturing.

Learning methods and activities

Lectures and project work, i.e., four hours of lectures and two hours of project work per week. The lectures are given in English. The flipped classroom will be used for some lectures. The students will complete four different projects assigned by the lecturers, with project reports expected to be written in English. The examination papers will also be given in English. Students are free to choose Norwegian or English for answering the exam.
