French Contributions to Metallurgy

THE well-known attention which has been devoted to the history of metallurgy by Sir Robert Hadfield receives an interesting supplement in a paper recently read (Oct. 5) in Paris at a congress of industrial chemistry organised by the French Society of Chemical Industry. The main theme of the address is the interrelation of British and French research in metallurgy, but the aspect, which to most readers will be found of the greatest interest, is the excellent resume given of the debt which this subject owes to French men of science. As an example, the author pays generous tribute to the importance, in connexion with his own discovery of manganese steel, of the investigations carried out by the Terre Noire Cie. on the commercial production of ferrous alloys very high in manganese.

The Journal of the Institute of Metals

THE increase of research in non-ferrous metallurgy is so rapid that succeeding volumes of the Journal of the Institute of Metals show a rapid growth in size. Volume 27 contains some interesting papers on re-crystallisation and grain growth. The paper by Mr. Adcock, containing a beautiful series of photographs illustrating recrystallisation in cupro-nickel, an alloy which proves very suitable for the purpose of this study, will be of material assistance in advancing the subject, which has been studied with such good results by Carpenter and Elam. Major Smithells' paper on grain growth in tungsten filaments makes use of the hypothesis of varying vapour pressure. Condenser tubes are considered from two points of view, the experience of the Corrosion Committee being utilised as a basis for recommendations as to their care in practice, while a second paper from the Research Department at Woolwich deals with the prevention of season cracking by the simple process of removing stress by low temperature annealing. The revision of the alloys of aluminium and zinc clears up some difficult points in the behaviour of this curious system, one of the most interesting in respect of its changes in concentration of solid solution with temperature. Several other papers deal with questions of practical importance, and the volume contains a very large number of abstracts of work published elsewhere.
