Abstract:

Production and Physical Metallurgy of Pure Metals -- Part II. An Improved Method of Preparing Iodide Chromium and its Properties. This is a translation of an article written V. S. Yemelyanov, A. I. Yevstyukhin, D. D. Abanin and V. I. Statsenko in Metallur- giya I Metallovedeniye Chistykh Metailov Production and Physical Metallurgy of Pure Matals, No. 1, Moscow, 1959, pages 44-62. Ductile chromium is of considerable interest to numerous branches of technology. Not until recently, however, has it been used as a structural metal, either in pure form or in alloys based on the pure form. This is to be explained by the fact that alumino-thermic chromium, as well as electrolytic chromium, as prepared at present is brittle and cannot be worked at room temperature. It has been used only for alloying steel and other alloys. Among the recent known methods of chromium refining, annealing in atmosphere of hydrogen, vacuum distillation, and the iodide method are worth noting. Despite the considerable attention paid by researchers to the two former methods, they do not yield chromium ductile at room temperature.
