CHE2167 · Process material selection

Overview

This unit introduces the basic concepts of materials properties and their selection for use in both the natural environment where they will be installed and the operating and process environment. The underlying philosophy of this unit will be used to compare different material selection options. The unit will include a fundamental understanding of static stress loading. It will include material degradation processes which may limit material life such as corrosion, embrittlement processes and oxidation processes. Through open-ended problems, you will develop technical knowledge and professional skills.

Assessment

The Handbook lists an examination for this unit.

Continuous assessment: 50% Final assessment: 50% This unit contains threshold hurdle requirements that you must achieve to be able to pass the unit. You are required to achieve at least 45% in the total continuous assessment component and at least 45% in the final assessment component. The consequence of not achieving a hurdle requirement is a fail grade (NH) and a maximum mark of 45 for the unit.

Assessment details may change. Please refer to the assessment information in Moodle closer to the start of the teaching period.

Requisites

Learning outcomes

1. Use appropriate representation (one-dimensional beam theory) of structures and diagrams (Mohr circle) to describe forces and stresses acting in a system and perform analysis of such structures in relation to chemical engineering design.
2. Solve the forces on solid structures in chemical engineering design problems.
3. Describe properties of materials and the link between the properties and uses for different applications.
4. Apply stress-strain relationships to determine elasticity of materials.
5. Explain corrosion mechanisms that can occur in common materials of construction and describe measures to mitigate corrosion.
6. Select materials of construction that are fit for purpose in design problems based on appropriate failure theories for engineering materials.
7. Have an appreciation for the role of a chemical engineer in the safe design of structures and their link with other disciplines in the engineering profession (e.g. mechanical and materials).

Workload

The minimum total expected workload to achieve the learning outcomes for this unit is 144 hours per semester typically comprising a mixture of 3-6 hours of scheduled learning activities and 6-9 hours of independent study per week. Scheduled activities may include a combination of teacher-directed learning, peer-directed learning and online engagement. Independent study may include associated readings, assessment and preparation for scheduled activities.

Student experience, not official rules. Nothing here changes what the Handbook says.
