FFY422   Deformation mechanisms in crystalline materials


For single subject courses within Chalmers programmes the same eligibility requirements apply, as to the programme(s) that the course is part of.

Course specific prerequisites

3 years of university studies (bachelor level, BSc, fil kand or equivalent) in Engineering Physics, Chemical Engineering, Mecanical Engineering, Materials Science, Physics or Chemistry.


To give a thorough understanding of the properties of dislocations and of how they are used to explain the plastic behaviour of crystalline materials.
To train technical report writing and oral presentation in English.


The first part of the course is a treatment of the geometry, properties and behaviour of individual dislocations. The elastic continuum is first discussed and the treatment is then extended to include some common crystal structures.
In the second part of the course, models based on these concepts are used to explain some of the mechanisms for plastic deformation, such as work hardening, solid solution and precipitation hardening, creep, fatigue and fracture.
The course concentrates more on a conceptual understanding of the behaviour of dislocations than on detailed calculations.


The first part contains 5 lectures, 4 problem solving lessons, and 5 laboratories (1. Plastic deformation, 2. Interstitials and dislocations, 3. Partial dislocations and stacking faults, 4. Hardening mechanisms, 5. Grain boundaries).
In the second part, each student is given as assignment to read an article on some topic within dislocation theory, to write a report (10 pages) summarising the topic, and to present the topic orally (20 minutes). All reports will be corrected and printed before the first oral presentation.
The course ends with a summarising lecture and a lesson in which some old exams are gone through.

Students' written reports


The assignment (written report and oral presentation) will be marked.
At the end of the course there will be a written examination which covers the whole course.
The mark of the course will be the mean of the mark of the assignment and the mark of the written examination.
