Abstract

As a result of the rapid growth of metallurgical know ledge, the difficulty found by new workers in collecting the existing information on any branch of the subject is becoming increasingly great. In an endeavour to overcome this, the American Engineering Foundation is publishing a series of monographs on the alloys of iron with the more important elements. So far, two volumes, dealing with molybdenum and silicon re spectively, have appeared, the latest jDeing concerned with the ferrous alloys containing tungsten. The abstracting is excellently done, and the information is clearly and logically presented. At the end of each chapter, the author has summarised the main con clusions which have been reached, not always an easy task as there is here and there some lack of concordance between the results of different workers. For the most part, however, the individual researches are considered uncritically—an eminently desirable procedure in the production of a book of the present type—and as a result it is at once clear where there is room for further work. The service which is being rendered to metallurgy by the publication of these monographs can scarcely be overestimated. This latest addition is most heartily to be welcomed, whilst the others in course of preparation on pure iron and its alloys with carbon, nickel and copper will be eagerly awaited.
