This text provides students with a solid understanding of the relationship between the structure, processing, and properties of materials. Authors Askeland and Wright present the fundamental concepts of atomic structure and the behavior of materials and clearly link them to the "materials" issues that students will have to deal with when they enter the industry or graduate school (e.g. design of structures, selection of materials, or materials failures). Fundamental concepts are linked to practical applications, emphasizing the necessary basics without overwhelming the students with too much of the underlying chemistry or physics.
- A new chapter on corrosion and wear has been added, extending the traditional Materials Science curriculum.
- Chapter learning objectives have been added to the beginning of each chapter to aid in the learning and retention of chapter content as well as to assist instructors with assessment instruments.
- Extended discussion of crystallography.
- New material on the allotropes of carbon added to the discussion on atomic structure.
- New current research topics and applications such as nanoindentation, mechanical behavior of metallic glasses, and mechanical behavior at small length scales.
- New material on the vapor-liquid-solid mechanism of nanowire growth.
- Problems have been added to the end of each chapter, some of which require students to use Knovel® online reference tool for Materials Science.
- Glossary items now in 2nd color for easier navigation.
- Content is in line with the latest advances in the field allowing students and faculty to make use of the ideas and issues that are of current interest.
- Students can relate the content to the products and technologies they have experience with through the real-world examples used through-out.
- Each chapter contains a "Have You Ever Wondered?" set of questions designed to pique the interest of students and set the framework for the material to be covered in that chapter.
- Uses an integrated approach to Materials Science and Engineering throughout.
