Abstract
458,315. Production by working of magnetizable iron-nickel alloys. COUTTS & CO., 440, Strand, London, and JOHNSON, F., 218, Victoria Drive, Eastbourne, [Representatives of JOHNSON, J. Y.).-(I. G. Farbenindustrie Akt. - Ges. ; Frankfort - on - Main, Germany) July 8, 1935, No. 19460. [Classes 83 (ii) and 83 (iv)] In the production of magnetizable alloys with iron and nickel contents and highly stable magnetically hot rolled material without any annealing is subjected to a strong cold deformation reducing the cross-section by at least 50 per cent followed by a soft annealing, preferably at 900‹ C., and generally not below 700‹ C. and finally to a cold deformation with a reduction of 40 to 60 per cent of the cross-section resulting from first deformation. The deformation may be all in the same plane and the same direction. The metals may be prepared from powders obtained from the corresponding metal carbonyls. The alloys may contain chromium, molybdenum, tungsten, silicon aluminium and copper. The product may be annealed at a temperature from 300 to 450‹ C.
