Timing and Structure

Weeks 1-8 Michaelmas term. 16 lectures, 2 lectures/week

Aims

The aims of the course are to:

  • Build on the Part IA Materials course to extend understanding of the relationships between processing, microstructure and properties.
  • Describe the thermodynamic and kinetic principles governing microstructural evolution in materials, and to model the evolution of microstructure and properties.
  • Develop understanding and modelling of deformation responses of materials.
  • Develop understanding of a range of other themodynamically-driven processes related to material properties and behaviour

Objectives

As specific objectives, by the end of the course students should be able to:

  • Understand the importance of temperature, composition and deformation in controlling the evolution of material microstructure and properties.
  • Understand and describe the concept of the thermodynamic driving force for microstructural change.
  • Understand how diffusion occurs, and derive and apply mathematical models of one-dimensional diffusion.
  • Understand the general principles in interpreting phase diagrams and the theory of phase transformations.
  • Apply these thermodynamic and kinetic principles and models to: (i) materials processing (e.g. solidification, precipitation in metals; crystallisation in polymers; doping of semiconductors).
  • Understand the analogy between mass diffusion and thermal diffusion.
  • Describe the mechanisms of temperature-dependent creep in metals.
  • Understand and model the deformation response of a range of engineering materials, including creep and metal forming processes.
  • Apply thermodynamic and kinetic principles to a range of material behaviour and processes including rubber elasticity and corrosion.

UK-SPEC

The UK Standard for Professional Engineering Competence (UK-SPEC) describes the requirements that have to be met in order to become a Chartered Engineer, and gives examples of ways of doing this.

UK-SPEC is published by the Engineering Council on behalf of the UK engineering profession. The standard has been developed, and is regularly updated, by panels representing professional engineering institutions, employers and engineering educators. Of particular relevance here is the 'Accreditation of Higher Education Programmes' (AHEP) document which sets out the standard for degree accreditation.

The Output Standards Matrices indicate where each of the Output Criteria as specified in the AHEP 3rd edition document is addressed within the Engineering and Manufacturing Engineering Triposes.
