Introduction to Engineering Materials and Aeromaterials (EAS107)

The course will provide students the basic foundation on the characteristics and applications of the more commonly used materials in the engineering and aerospace industries, including ferrous and non-ferrous metals, ceramic materials, polymers and composites. The various material designation systems will be covered as this will facilitate materials selection. The significance of mechanical behaviours in the performance of the materials and the test methods to determine these behaviours will be taught. The effects of mechanical, thermal and thermo-mechanical treatments on properties will be examined. These include cold and hot working, solidification and heat treatment processes. Phase diagrams will be used to explain the transformations which occur when materials are being strengthened. Imperfections in atomic arrangements, diffusion mechanisms and their applications in materials processing will also be highlighted.
