Review Of Metallurgical Technology

THERE are two recognized methods of recording the state of the metallurgical art. One involves delineation of individual advances reported in the literature. This approach is used effectively in the excellent annual reviews published by some of the leading technical journals and in the technology sections of the individual commodity chapters in this volume. In an effort to more clearly indicate the current trend of metallurgical research and development, the authors of this chapter chose the method of discussing generally selected items of interest brought to their attention during 1959. Since technology cannot be confined by dates on a calendar, most of the items mentioned have been in the process of development for several years. No attempt was made to identify the sources of information used here. Material was drawn from many sources : Nonconfidential correspondence and conversations with authorities of the metallurgical fraternity, papers delivered at technical meetings, and articles noted in the technical press, including particularly Engineering and Mining Journal, Metal Progress, Journal of Metals, Mining Engineering, Industrial and Engineering Chemistry, Chemical Engineering, Chemical and Engineering News, Chemical Week, Materials in Design Engineering, Review of Metal Literature, the Canadian Mining and Metallurgical Bulletin, the Mining Journal (British), and the Journal of the Institute of Metals (British).
