Materials processing; phase transformations in metals and alloys; aluminium and ferrous alloys.
This course introduces students to the material thermodynamics and kinetics that underpin the materials science and engineering from introductory courses. Students will gain a deeper understanding of structure-processing-property-performance relations in metallic systems through lectures and laboratories.

Please refer to the course Learn page for details of assessment information.
Lecture Handouts:Lecture slides are posted to LEARN. Some additional slides may be made available before lectures in Lecture section of the LEARN site. You should bring slides to the lectures to annotate on either a soft or hard copy.Required Reading Material:Reading assignments will be given throughout the term. Completion of these assignments is essential for the course. To maximise learning, you must complete the reading from the required text, selected chapters of other books that will be posted on LEARN, and the additional references posted on LEARN.
