Engineering materials is the study of the manufacture of new materials that provide solutions to a variety of problems. This field is a synthesis of various other scientific branches such as ceramics, metallurgy, chemistry and solid-state physics. Biomaterials, electronic materials such as semiconductors, optoelectronic devices, etc. are some of the widely used materials. The objective of this book is to give a general view of the different areas of engineering materials and their applications. The book is appropriate for students seeking detailed information in this area as well as for experts.
