Dissemination of IT for the Promotion of Materials Science (DoITPoMS)

DoITPoMS TLP Library

TLP Library

Teaching and learning packages (TLPs) are self-contained, interactive resources, each focusing on one area of Materials Science.

TLPs containing HTML5 animations/simulations are labelled with the tag . We have found that often the HTML5 animations render better in Microsoft Edge, so if your favourite browser does not work very well with them, please try an alternative.

Atomic Force Microscopy

Provides a brief introduction to atomic force microscopy (AFM), some of the ways it is commonly used and some of the problems faced.

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.

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.

Diffraction and Imaging

A brief summary of diffraction and imaging using an optical system.

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.

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.

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.

Optical Microscopy

An introduction to the use of optical microscopes. It introduces the different types of microscope used to examine specimens and how to set them up correctly. There is also an introduction to specimen preparation.

Introduction To Photoelasticity

This tutorial is based on lab work within the Department of Materials Science and Metallurgy at the University of Cambridge. The tutorial provides an introduction to the topic of photoelasticity and preparation for lab work. Photographs illustrate many features of birefringence in polymers under polarised light.

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.

Transmission Electron Microscopy

Transmission electron microscopy is a very important tool in materials science for investigating the fine-scale structure of materials. This TLP serves as an introduction to the basic concepts and structure of the transmission electron microscope.

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.
