Materials engineering is an interdisciplinary branch of engineering which studies the various properties of different materials. It makes use of the principles of mechanical, electrical and civil engineering along with basic sciences to study the fundamental physical as well as chemical properties of the existing materials and then create new materials with desired properties. Some of the key areas of focus of this subject are atomic structure, crystallography, macrostructure and nanostructure. Emerging fields such as polymer and ceramic engineering are also its sub-branches. Polymer engineering deals with the study of materials such as thermoplastics, elastomers and thermosets. While ceramic engineering is concerned with the creation of objects from inorganic and non-metallic compounds. In the last few decades, material science and engineering has developed at a rapid pace. Some of the important innovations in the field of materials engineering are transistors, rockets, kevlar, etc. Different approaches, evaluations and methodologies and advanced studies on materials engineering have been included in this book. The topics included in this book on materials engineering are of utmost significance and bound to provide incredible insights to readers. It will serve as a valuable source of reference for those interested in this field.
