The fifth edition of this successful textbook continues to provide an introduction to the basic principles of materials science over a broad range of topics, current applications, and recently developed materials. Materials Science for Engineers, 5th Edition includes an expanded treatment of many materials, particularly polymers, foams, composites and functional materials. Superconductors and magnetics receive greater coverage to account for the considerable development in these fields in recent years. New sections on liquid crystals, superalloys, and organic semiconductors have also been added to enhance this textbook's coverage of materials science.
