Metals and Alloys

Recommended Prerequisites

Not aplicable.

Teaching Methods

Material is delivered through lectures, group learning and practical sessions. It is assessed through four MCQ tests, one assignment and the exam. Students will have to submit reports as well as do oral presentation as part of the assignment.

Learning Outcomes

The objective of this module are;

- to apply a knowledge gained of the processing-microstructure-property relationship to the design of alloys for structural applications;

- to illustrate the state-of-the-art in some conventional structural alloys and show how research has, and continues, to inform the design of these materials;

- to develop the student's understanding of this process and provide an opportunity for them to carry this out in designing an alloy to a properties brief.

Work Placement(s)

No

Syllabus

- Foundations of physical metallurgy: phase diagrams and phase equilibria; metallic crystal structures and microstructure; mechanical properties, deformation and strengthening mechanisms.

- Ferrous metallurgy: carbon and nitrogen in steel - solubility, ordering, carbide precipitation; strain ageing; microalloyed steels; grain size, shape, stability; control of grain size; inclusions in steel; case studies in carbon steels; low alloy steels; maraging; ausformed and TRIP steels; stainless steels; welding and weldability; cast irons.

- Non-ferrous metallurgy: alloy designation and physical metallurgy of cast and wrought Al, Mg and Ti alloys; mechanical properties, corrosion behaviour, fabrication, applications; superalloys-classification, physical metallurgy, mechanical properties, processing, application; copper alloys-characteristics of phase diagrams, properties of pure Cu, brasses, simbronzes and monels; precious metals-gold, silver, platinum, palladium; lead; tin and zinc alloys.
