Module summary

This module will provide a fundamental understanding of the relationship between materials properties and their microstructure. It will give the necessary background to understand the design of suitable microstructures to give desired properties across the full range of materials classes.

Objectives

The objectives of this module are to:

- apply a quantitative treatment to the properties of materials, and their origin;
- provide the scientific basis for the relationship between materials properties and their microstructure;
- give students the necessary background to understand the design of suitable microstructures to give desired properties across the full range of materials classes.

Learning outcomes
On successful completion of the module students will have demonstrated the following learning outcomes relevant to the subject:

1. Be able to apply a continuum approach to the elastic and plastic deformation of materials.
2. Understand the origins of elastic behaviour of solids and its relationship to structure.
3. Understand the principles of non-linear elasticity.
4. Understand the origin and application of linear elastic fracture mechanics to brittle fracture and fatigue crack growth.
5. Understand the macroscopic aspects of the deformation and failure of materials by fatigue and creep and perform simple calculations to predict the lifetime of a component subjected to fatigue or creep using data obtained from standard tests.
6. Understand the micromechanics of deformation and fracture in materials, their relationship to structure, and the principles of microstructural engineering to control mechanical behaviour.
7. Understand the influence of composition and structure on the physical and thermal behaviour of materials by applying classical and quantum mechanical approaches.
8. Understand the mechanisms of interaction of materials with their environment: oxidation, corrosion, and degradation.
9. Be able to apply thermodynamic and kinetic principles to the analysis and prediction of rates of corrosion, oxidation and degradation.
10. Understand the influence of composition and structure on the chemical interaction of materials with their environment.
11. Be able to discuss the selection, performance and protection of materials in aggressive environments.
12. Apply a comprehensive knowledge of mathematics, statistics, natural science and engineering principles to the solution of complex problems. Much of the knowledge will be at the forefront of the particular subject of study and informed by a critical awareness of new developments and the wider context of engineering.
13. Select and critically evaluate technical literature and other sources of information to solve complex problems.
14. Design solutions for complex problems that evidence some originality and meet a combination of societal, user, business and customer needs as appropriate. This will involve consideration of applicable health & safety, diversity, inclusion, cultural, societal, environmental and commercial matters, codes of practice and industry standards.

Skills Learning Outcomes
On successful completion of the module students will have demonstrated the following skills:
a. Technical skills
b. Information skills
c. Design skills
