A material is that from which anything can be made. It includes wide range of metals and non-metals that are used to form finished product. The knowledge of materials and their properties is of great significance for a design engineer. Material science is the study of the structure-properties relationship of engineering materials such as ferrous; non-ferrous materials, polymers, ceramics, composites and some advanced materials. Metallurgy is the study of metals related to their extraction from ore, refining, production of alloys along with their properties. The study of material science and metallurgy links the science of metals to the industries. Also this helps in completing demands from new applications and severe service requirements.
