| Module Description: |
This module will provide the student with an understanding of the relationship between material structure and material behaviour or performance. It will classify different materials e.g. metals and plastics according to their properties. The relationship between cooling or quenching rate and the properties and microstructure of steel is outlined. Classification of composite materials according to their reinforcement is described.

| Learning Outcomes |
| On successful completion of this module the learner will be able to: |
| # |
Learning Outcome Description |
| LO1 |
Relate cooling rate and alloying to specific material properties and end use applications of plain carbon steels. |
| LO2 |
Identify limitations that impact the performance of
engineering materials. |
| LO3 |
Discuss recent advances in engineering material in areas such as aerospace and biomedical. |
| LO4 |
Select suitable materials for a particular design or application subject to appropriate design constraints
whilst being mindful of economic, environmental and societal issues. |
| LO5 |
Structure and prepare a technical report on mechanical properties measurement or materials selection. |

Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named MTU module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
|
|
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
|
| No incompatible modules listed |
Co-requisite Modules
|
| No Co-requisite modules listed |
Requirements
This is prior learning (or a practical skill) that is mandatory before enrolment in this module is allowed. You may not enrol on this module if you have not acquired the learning specified in this section.
