Overview
This unit is concerned with the mechanisms of deformation and strengthening in crystalline and non-crystalline solids.
Aims
The unit aims to:
Provide an overview of the deformation mechanisms in crystalline and non-crystalline solids.
Provide a quantitative treatment of the strengthening mechanisms using simple physical models.
Provide a theoretical framework for the time dependent deformation of non-crystalline solids and how it is affected by microstructure.
Learning outcomes
A greater depth of the learning outcomes will be covered in the following sections:
- Knowledge and understanding
- Intellectual skills
- Practical skills
- Transferable skills and personal qualities
Teaching and learning methods
Lectures, group tutorials (problem sessions), recommended textbooks, web resources, past exam papers, electronic supporting information (Blackboard), peer-assisted study sessions (PASS).
Knowledge and understanding
Understand the origins of the strength of solids and its link to structure and microstructure.
Understand the physical mechanisms of plastic deformation in crystalline solids.
Know the concepts of slip, cross-slip, climb, diffusion and twinning.
Recognize the different defect types in crystalline solids and understand the role they play in plastic deformation.
Understand the concept of stored energy.
Understand the mechanisms that give rise to work hardening.
Know and understand how crystalline solids are strengthened by solid solution, grain size, and second phase particles.
Understand the effect of temperature on deformation mechanisms.
Understand the mechanisms responsible for viscoelasticity and how it depends on the molecular structure.
Understand the glass transition phenomenon, factors that affect it and how it can be determined.
Intellectual skills
Show improved logical reasoning, problem solving and ability in applied mathematics.
The ability to use simple models to calculate the strength of crystalline solids.
Practical skills
Use bend testing and microscopy to investigate the strengthening mechanism of light alloys
Carry out and interpret experiments to determine the glass transition temperature.
Transferable skills and personal qualities
Convert word problems into equations and numerical answers.
Develop techniques for estimating the results from calculations.
Work effectively in a group to solve problems.
Compose simple technical reports on laboratory tests.
