Materials Technology 3

The course gives an introducton to material production from raw material to product with emphasis on metals/semiconductors such as Iron/Steel and Silicon. The course will also provide skills in high-temperature laboratory work, report writing and oral presentation. The course is in part a continuation of the courses TMT4171 Materials Technology 1 and TMT4176 Materials Technology 2 (see course description for 2015/16).

The course provides an introduction to the production of materials from raw materials to products with emphasis on metal / semiconductors as iron / steel and silicon. Basic chemical prerequisites and energy / environmental aspects of materials production will be covered. The course also provides an introduction to optical, magnetic and electrical properties of materias. The course gives a more comprehensive approach to mechanical properties of materials with respect to the concepts of stresses and strains, and the simplest possible mathematical treatment of these. Together with the elasticity theory covered in the course, this gives basic knowledge for later courses covering basic dislocation theory and the mechanisms behind the mechanical properties of metals.

After completing the course the student will:
- Be familiar with and describe the chemical conditions and production methods for iron / steel and silicon.
- Apply basic thermodynamic knowledge to calculate the production temperatures and stable phases in metal production.
-Be able to explain the environmental impact and energy use in material production.
- Have basic knowledge of functional materials and in addition have a certain numerical understanding of the factors that affect their electrical, optical and magnetic properties.
- Derive strain and stress components in a rotating coordinate system.
- Determine the stress and strain.
- Derive and apply the beam equation to calculate the stresses in and deflection of simple beam structures.
- Generalize elasticity theory for a tension rod to an isotropic linear elastic theory for small strains.
- Explain what a flow criterion is and discuss its flow surface.
- Be able to write a simple research / laboratory report (as a group) from a fixed template.
- Be able to prepare good presentations in PowerPoint and lecture on their projects to fellow students in class.
