Abstract

This book treats a quantum approach to alloy design developed on the basis of a molecular orbital method. In view of the electron bonding, it is no longer needed to distinguish between iron and steels and nonferrous alloys, and even the current classification into metals, semiconductors, ceramics and polymers is not necessarily required. The present quantum approach is useful not only for the fundamental understanding of alloys, but also for alloy design without relying on trial-and-error experiments.
