PREFACE TO SECOND EDITION
ADVANTAGE has been taken of a reprinting to revise, extensively,the portions of the book relating to the modern science of metallography.
Considerable of the matter relating to the influence of chemical composition upon the properties of alloy steels has been rewritten.
Furthermore, opportunity has been taken to include some brief notes on methods of physical testing whereby the metallurgist judges of the excellence of his metal in advance of its actual performance in service.
