This is an introductory text for materials science and engineering. This book takes an integrated approach to materials, with an organization focusing on properties rather than classes of materials.Schaffer's Science and Design of Engineering Materials, 2nd Edition will now be complemented by an e-Text. An e-Text is pdf. files of the mian text on CD-ROM. The entire contents of the Materials in Focus CD-ROM, which has previously complemented the book are also on the e-Text. Because the text and the Materials in Focus CD-ROM are now together on one CD-ROM, students are able to move back and forth between the two seamlessly. Instructors will benefit from the e-Text because they will better be able to tie the text material to lectures and homework problems.
