Sample Learning Outcomes
METALLIC MATERIALS
The following could serve as a model set of outcomes for the successful student. This set is illustrative only and is presented by the committee as an example of what it envisages could be taught about corrosion to a range of engineering students and graduates. The committee does not purport that these lists of outcomes are complete. Establishing a complete and comprehensive set of outcomes would require an effort beyond the scope of this study.
Undergraduate Engineering Students in Design Disciplines (Mechanical, Civil, Chemical, Industrial, Aeronautical)
Be aware of general properties of classes of materials.
Understand that properties can be affected by processing.
Know that resources exist for aiding materials selection.
Understand that trade-offs in properties are often required—between, for example, strength and ductility.
Know that material properties degrade with time in an aggressive environment.
Know that the degradation of properties must be considered in design processes.
Know that there are different approaches to designing against corrosion.
