Atomic Theory for Students of Metallurgy 3rd Edition PDF

During the preparation of this revised reprint metallurgy lost one of its most distinguished scientists, and the writer a wise teacher and generous friend, with the death of Professor Hume-Rothery. Among his great gifts was an insight into the changing needs of metallurgy students, and the present book appeared first when wartime experience had shown that physical metallurgists would need to draw upon knowledge of the electronic structures of metals (as well as their crystal structures and phase constitution) to understand both their alloying behaviour and their physical properties. Increasingly the metallurgist was being asked to produce alloys and intermetallic compounds whose applications depended upon their electronic rather than their mechanical properties. Professor Hume-Rothery thus anticipated much of the thinking that has led to undergraduate and postgraduate courses in the Science of Materials. Because of his death the revisions of the later sections of this revised reprint have not had the benefit of his gift for combining in the highest degree clarity of expression and scientific accuracy, but the general pattern of the cha.nges made had been discussed between us.

The principal changes have been hrought about by improvements in the confidence that can be given to theoretical calculations of electronic structures, the increasing volume of direct experimental evidence about electronic structures, and the possibility of correlating with these structures many of the macroscopic physical properties. There have therefore been significant additions to Chapters 25 and 26, the addition of short new chapters on rare-earth metals and dilute alloys in Part VI and the creation of a new Part VII on physical properties to include accounts of electrical resistivity and superconductivity, as well as the former chapter on magnetic properties to which a section on the l\tlossbauer effect has been added. Since this is a revised reprint, not a new edition, no effort has been made to modify the units in which physical quantities are expressed to the 81 system.

My thanks are due to many colleagues for helpful discussions, to Mr. ,Tohn Dunlop for the preparation of the indices, and to Mrs. A. D. Moss for help in the correcting of the proofs
