Help your students understand the science of materials in order to select and deploy materials as responsible engineers with Askeland/Wright's ESSENTIALS OF MATERIALS SCIENCE AND ENGINEERING, 4TH Edition. Your students develop a foundational understanding of why materials behave the way they do, and how they are best used in actual engineering practice. Students learn why materials display certain properties as they study how the structure and processing of materials results in these properties. The authors link fundamental concepts to practical applications, emphasizing the necessary basics without overwhelming readers with too much underlying chemistry or physics. This presentation is ideal for an introductory science of materials class taught at the sophomore or junior level and assumes knowledge of first-year courses in college-level chemistry and physics.
