Introduction To Anisotropy
It is common in basic analysis to treat bulk materials as isotropic - their properties are independent of the direction in which they are measured. However the atomic scale structure can result in properties that vary with direction. This teaching and learning package (TLP) looks into typical examples of such anisotropy and gives a brief mathematical look into modelling the behaviour.
Batteries
This TLP investigates the basic principles, design and applications of batteries. It covers both primary and rechargeable batteries, how they work and how they may be used.
Brillouin Zones
This teaching and learning package provides an introduction to Brillouin zones in two and three dimensions and is aimed at developing familiarity with Brillouin Zones. It will not cover any specific applications. Brillouin Zones are particularly useful in understanding the electronic and thermal properties of crystalline solids.
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.
Creep Deformation of Metals
Creep is a major concern in engineering, since it can cause materials to fail well below their yield stress. This package outlines the mechanisms of creep and the associated equations. It is largely based around a first year Materials Science practical at the University of Cambridge, which is concerned with the creep of solder at different temperatures. It also includes a case study of a creep-resistant material to illustrate how materials can be designed to prevent creep.
Crystallographic Texture
This teaching and learning package (TLP) introduces the concept of texture in crystalline materials such as common metals and metallic alloys.
Crystallography
Crystalline materials are characterised by a regular atomic structure that repeats itself in all three dimensions. In other words the structure displays translational symmetry.
Introduction To Deformation Processes
This teaching and learning package covers the fundamentals of metal forming processes.
Diffusion
An introduction to the mechanisms and driving forces of diffusion, and some of the processes in which it is observed.

Electromigration
Electromigration is an ever-increasing problem as integrated circuits are pushed towards further miniaturization. The theory of the phenomenon is explained, including electromigration-induced failure and how it has been and can be minimized.
Ellingham Diagrams
The Ellingham diagram is a tool most often used in extraction metallurgy to find the conditions necessary for the reduction of the ores of important metals. This Teaching and Learning Package incorporates an interactive Ellingham diagram. This diagram can be used to quickly and simply find a range of thermodynamic data relating to many metallurgical reactions.
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.
Ferromagnetic Materials
How many ferromagnets do you think you own? Maybe many more than you realise. Ferromagnetic materials lie at the heart not just of the humble compass, but also of many loudspeakers and of computer memory. This teaching and learning package outlines the microscopic basis of magnetism and some of the conquences of ferromagnetic order in real materials.
Fuel Cells
This teaching and learning package provides a short summary of four of the most promising fuel cell technologies. It gives a general overview of the field with focus on materials used (electrolytes and electrodes) and the mechanism of function (electrochemistry and thermodynamics).
Indexing Electron Diffraction Patterns
An introduction to the indexing of diffraction patterns.

Lattice Planes and Miller Indices
This teaching and learning package provides an introduction to the method used to describe planes of atoms in a crystalline material. The practical uses of describing planes of atoms are also addressed.
The Nernst Equation and Pourbaix Diagrams
This teaching and learning package (TLP) investigates the Nernst equation and Pourbaix diagrams, which are both important parts of electrochemistry and corrosion science.
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.
Recycling of Metals
The next time you drain a canned beverage or take a journey in a car, you might like to think about what will happen to it when it reaches the end of its useful life. This teaching and learning package will look at metals recycling from a materials science viewpoint – not simply outlining the need for recycling, but explaining the complex scientific principles behind some aspects of the recycling process itself.

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.
Solidification of Alloys
This teaching and learning package (TLP) is an introduction to how solute affects the solidification of metallic alloys.
The Stereographic Projection
This TLP covers the use of the Stereographic projection and Wulff nets.
Superconductivity
Electrons in pairs? Levitating trains? Superconductivity - the combination of lossless electrical conduction and the ability of a material to expel a magnetic field - is a property that excites interest in fundamental science whilst offering tantalising prospects for a range of applications. In this teaching and learning package (TLP), we trace the history of superconductivity, outline some fundamental properties of superconductors, and describe current and potential applications of materials with this unusual property.
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.
