TAILIEUCHUNG - Materials Science And Engineering An Introduction

In this Eighth Edition we have retained the objectives and approaches for teaching materials science and engineering that were presented in previous editions. The first, and primary, objective is to present the basic fundamentals on a level appropriate for university/college students who have completed their freshmen calculus, chemistry, and physics courses. In order to achieve this goal, we have endeavored to use terminology that is familiar to the student who is encountering the discipline of materials science and engineering for the first time, and also to define and explain all unfamiliar terms. The second objective is. | MATERIALS SCIENCE AND ENGINEERING AN INTRODUCTION EIGHTH EDITION David G.
