Analysis of Deformation Processes
This TLP builds upon the introduction to yield criteria covered in the Stress analysis and Mohr's circle TLP and introduces a range of methods commonly used to study metal forming processes.
Brittle Fracture
What determines when a material will break, and whether failure will be catastrophic or more gradual. Cracking is controlled by the energy changes that occur - it is not the stress at the crack tip that is important..
Casting
This TLP introduces a number of important processes through which metallic items can be fabricated from molten metal. As well as detailing the practical aspects of these manufacturing processes, attention is given to the important parameters which determine the microstructure of the finished items.
Crystallinity in Polymers
An understanding of polymer crystallinity is important because the mechanical properties of crystalline polymers are different from those of amorphous polymers. Polymer crystals are much stiffer and stronger than amorphous regions of polymer.
Crystallographic Texture
This teaching and learning package (TLP) introduces the concept of texture in crystalline materials such as common metals and metallic alloys.
Introduction To Deformation Processes
This teaching and learning package covers the fundamentals of metal forming processes.
Introduction To Dislocations
Dislocations are crucially important in determining the mechanical behaviour of materials. This teaching and learning package provides an introduction to dislocations and their motion through a crystal. A 'bubble raft' model is used to demonstrate some of the features of dislocations and other lattice defects. Some methods for observing real dislocations in materials are examined.
Examination of a Manufactured Article
This TLP provides an introduction to the deconstruction and investigation of the materials and processes used in an everyday item or article.
Ferroelectric Materials
Ferroelectrics are an important device in today's world. They are useful both as capacitors, for example in camera flashes, or as non-volatile memory storage. The memory use of which you are most likely to be aware is in the Playstation 2.
Indexing Electron Diffraction Patterns
An introduction to the indexing of diffraction patterns.

The Jominy End Quench Test
Discusses the aims, method and use of results of a test for the hardenability of steel.
Introduction To Mechanical Testing
This teaching and learning package is based on laboratory experiments used in the Department of Materials Science and Metallurgy at the University of Cambridge. The package looks at how the microstructure of a material can affect its properties. It is split into two experiments: the first part introduces tensile testing and stress-strain curves, while the second part uses three-point bending, as introduced in the Beam Stiffness TLP.
Microstructural Examination
This teaching and learning package (TLP) looks at how what we see in micrographs relates to equilibrium phase diagrams and cooling routes for alloy systems.
Reciprocal Space
This TLP shows the construction of reciprocal lattices from real ones, use of the Ewald sphere for diffraction experiments and some other applications of reciprocal space.
Slip in Single Crystals
This teaching and learning package explains how plastic deformation of materials occurs through the mechanism of slip. Slip involves dislocation glide on particular slip planes. The geometry of slip is explained, and electron microscopy techniques are used to show slip occurring in single crystals of cadmium.
The Stereographic Projection
This TLP covers the use of the Stereographic projection and Wulff nets.
Stress Analysis and Mohr's Circle
This teaching and learning package provides an introduction to the theory of metal forming. It discusses how stress and strain can be presented as tensors, and ways of identifying the principal stresses. Suitable yield criteria to treat metals and non-metals are also presented.
X-ray Diffraction Techniques
This teaching & learning package provides an introduction to X-ray diffraction. It describes the main crystallographic information that can be obtained and experimental methods most commonly used.
