Book excerpt: Excerpt from The South African Mining Journal, Vol. 25: With Which Is Incorporated "the South African Mines, Commerce and Industries;" June 24, 1916; Part II At the first meeting of the Standing Committee on Metal lurgy appointedby the Advisory Council Scientific Research. For Scientific and Industrial Research, Sir R. Hadfield, as Chairman of the Ferrous Section, called attention to the necessity for im provement and progress in the metallurgy. Of. Iron and steel. Though Great Britain had been far from backward in this field, there was now room for a great'extension of research, in which there would be a happy combination of science and practice. The further progress of metallurgy depended largely on the securing of supplies of the special alloys and materials required, and there was now need for a-central clearing-house in order that asnsoon asnew knowledge was 0 secured as to valuable products in any part of the Empire, it should be made available for British industry. No foreign control of such products should any longer be permitted. Sir Robert called attention to the series of special reports on the mineral resources of Great Britain now being issued by the Geological Survey, and urged that similaryinforma tion for the. Whole Empire should now be made available through one central source. He directed attention to a number of subjects upon which more light was needed - for example, the production of sound steel; 'the discovery of new alloy steels and the development of the older types: wider study of crystallised structure and examination by photomicrography with increased magnifications; more accurate determinations of high temperatures, including the improvement of electrical and optical pyrometers; the im provement of methods of hardening; the improvement of the permeability and other electrical and magnetic qualities of various alloys, and the correlation of the mechanical and magnetic properties of steel; corrosion refractory materials, especially with a vll'w to rendering ourselves independent of foreign supplies.
