Phase transitions - 1

To paraphrase Cottrell, "there are three main frontiers of science today. First, the science of the very large, i.e., cosmology. Second, the science of the very small, the elementary particles of matter. Third, and by far the largest is the science of the very complex, which includes materials science." In fact, the complexity of structures in a materials is impressive; its control by manipulating phase transformations helps achieve a huge range of useful properties. A "phase transformation" involves a change in atomic arrangement but there may also be a change in chemical composition. An understanding of these changes is essential in the design of new materials, and the optimisation of existing materials for challenging conditions. This is the first of a set of lectures designed to introduce the concepts to undergraduates. The course is given by Harry Bhadeshia and Haixue Yan at Queen Mary University of London.
