UNIT 25: MECHANICAL BEHAVIOUR OF METALLIC MATERIALS
Unit 25: Mechanical Behaviour of Metallic
Materials
Level: 3
Unit type: Internal
Guided learning hours: 60
Unit in brief
Learners investigate and conduct tests on the mechanical properties of metals, consider suitable
applications and explore failure modes to improve component design.
Unit introduction
Selecting the most appropriate material and processing method for an engineered product or
system is critical to ensure that it is fit for purpose. The materials used in the airframe of an
aeroplane, car body pressings, cast components in domestic appliances and the ‘T’-shaped
electricity pylons (in the UK) all require careful selection and testing of appropriate metallic
materials.
In this unit, you will investigate and research the microstructures of ferrous and non-ferrous
metallic materials, some of which will have been processed, for example heat treated. You will use
a metallurgical microscope to inspect the microstructures of the materials you are investigating.
You will also undertake destructive and non-destructive tests on the materials and use the results
of the experimentation and research to determine the mechanical properties of, and suitable
applications for, the materials. Finally, you will examine the reasons why components have failed
in service and consider possible design improvements that could prevent failure.
As an engineer it is important to know about and understand the capabilities of a range of metallic
materials to create products and systems that are suitable for application. This unit will help to
prepare you for an apprenticeship or a technician-level role in industry. It will also help to prepare
you for a range of higher education courses, such as a Higher National Diploma (HND) or a degree
in any engineering discipline.
Learning aims
In this unit you will:
A Investigate the microstructures of metallic materials, the effects of processing on
them and how these effects influence their mechanical properties
B Explore safely the mechanical properties of metallic materials and the impact on
their in-service requirements
C Explore the in-service failure of metallic components and consider improvements to
their design.
