Lärandemål

After a successful course, the student shall

Kunskap och förståelse

- display knowledge of and be able to understand the various types of failures their mechanisms (Static and fatigue), and the material/process related reasons behind failure
- display detailed knowledge of the cast metal microstructural features and their role on the failure (Cast Iron, Al, and Mg)

Färdighet och förmåga

- demonstrate the ability to apply different analytical techniques to determine the cause of the failure and recognize the possible factors leading to materials failure
- demonstrate skills on how to plan, control and conduct a failure analysis process
- demonstrate the ability to identify the impact of different environmental (temperature, work environment, processing etc) conditions on the deformation and crack growth of cast metals.

Värderingsförmåga och förhållningssätt

- demonstrate the ability to choose the right methodology for conducting analysis and processing to provide root causes for a failure
- demonstrate an understanding of the various root causes (material, design, operational) of the failure and determine the exact failure mechanism.

Innehåll

The course gives knowledge of various failure mechanisms and methodology of failure analysis especially in cast metals. The various factors behind the failure from aspect of materials, design, processing and operational parameters are discussed. It covers the deformation of cast metals at both room and elevated temperature and provides knowledge on fracture mechanics. The environmental factors such as temperature and corrosion affecting the failure are studied. The approach, planning and execution of failure analysis process and related analytical techniques are also discussed.

The course includes the following elements:
- Structure of metals
- Failure modes in cast materials: ductile and brittle fracture, fatigue, creep
- Analysis methods for the study of fracture surfaces
- Plastic deformation, crack nucleation and growthmechanism
- Study of environmental factors (temperature, corrosion) and related failures
- General outcomes and discussion about failure analysis
