HIORNS HEAD OF METALLURGICAL DEPARTMENT, BIRMINGHAM SECOND EDITION COMPLETELY REVISED AND ENLARGED London MACMILLAN AND CO., LIMITED NEW YORK: THE MACMILLAN COMPANY 1901 All rights reserved PREFACE TO THE SECOND EDITION ADVANTAGE has been taken of the issue of another edition to thoroughly revise and amplify the work, so as to include some of the results of recent research. Great advances have been made in the study of alloys during the last seven or eight years, notably by Roberts-Austen, Charpy, Osmond, Le Chatelier, Wright, Moissan, Stead, Heycock and Neville, etc., and references have been made to the published works of these and other eminent authorities. M H. Le Chatelier, in the preface to the French translation of the present work, points out that the scientific study of alloys has not yet been sufficiently matured to permit of placing the subject on a logical scientific basis, and judging by the experience of different branches of applied chemistry, such as dissolution, fractional distillation, dissociation, etc., it will take about twenty-five years to enable the new theories to be properly sifted, tested, and co-ordinated, as well as to suitably connect such a scientific basis with practical industry. During this elaboration, the present work, it is hoped, will be a useful guide to manufacturers, workers, and students who are interested in the practical applications of metallic alloys.
