Unit Description and General Aims

Mechanical engineers must have a sound knowledge of materials; their properties, how to work them and maintain them. Materials in the 21st century are not only metals but a large range of plastics, elastomers, ceramics but even types of wood.
The student will obtain a sound knowledge of the metallurgy of both ferrous and non-ferrous metals as well as working knowledge of alloys and eutectic systems. The principles of heat treatment, forming, joining metals by various means, surface treatments to enhance required properties or to provide corrosion protection will be discussed.
The uses of various types of engineering plastics will be explained; students will recognise their advantages and limitations. Composite materials (GRPs, for instance) and their repair in practice will be explained. The student will appreciate how materials are converted into useful artifacts by using 3D methods.

Learning Outcomes

On successful completion of this Unit, students are expected to be able to:

  1. Evaluate how materials have shaped societies throughout history.

  5. Critique material testing and implement collaboration with others in undertaking tests and reaching conclusions.
    • Bloom’s Level 5
  6. Synthesise material data sourcing and compare materials, by calculation where necessary. To decide, considering all factors especially engineering, social, environmental and economic, which materials best meet the particular requirements
    • Bloom’s Level 6
