Engineering Materials: Properties and Selection
For courses in Metallurgy and Materials Science.
Co-authored by Kenneth G. Budinski and Michael K. Budinski, his son, with over 50 years of combined industry experience in the field, this practical, understandable introduction to engineering materials theory and industry-standard selection practices provides students with the working knowledge to (1) make an informed selection of materials for engineering applications and (2) correctly specify materials on drawings and purchasing documents. Encompassing all significant material systems metals, ceramics, plastics, and composites this text incorporates the most up-to-date information on material usage and availability, addresses the increasingly global nature of the field, and reflects the suggestions of numerous adopters of previous editions.
