Module Description: This introductory course in Materials Science and Engineering aims to provide students with an insight into how to select the most appropriate material for a given application which satisfies certain design criteria. The relationships between material structure, processing or manufacture and material properties is described particularly for metallic materials and specifically steel. The course has a detailed practical programme where students will learn how to measure and tensile, impact and hardness properties of certain metals and characterize their microstructure. Students will be expected to write reports on their laboratory work. Students will use material selection software to help identify the choice of optimum material based on differing criteria for specific applications.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Identify and describe the basic mechanical properties, behaviour, limitations or performance of engineering materials
LO2 Explain the interaction between atomic structure and mechanical properties
LO3 Measure and characterise the mechanical behaviour or microstructure of a material
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
Pre-requisite learning
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 CIT 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.

No requirements listed
