This edition has been revised throughout and now includes coverage of the use of new materials in engineering, materials for bearings and tribological usage, and the use of materials in civil engineering structures. It has also been expanded to include more case studies and worked examples in order to provide tangible and interactive contact with the content matter. The book also contains a detailed consideration of the weldability of steels, the welding of plastics and adhesion programs. An example of this development is the inclusion of a chapter detailing the use of materials in automobile structures; a field in which the traditional use of steel is being displaced as the application of reinforced polymers becomes more widespread. The book also reflects the growing use of computerized databases and materials selection programs.
