| abstract | 558,738. Decarbonizing iron alloys. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken.). Oct. 24, 1941, No. 13948/43. Divided out of 558,709. Drawings to Specification. [Classes 72 and 82 (i)] In the manufacture of material of high magnetic conductivity in all directions, an alloy containing equal parts of iron and cobalt, to which is added manganese, aluminium or silicon or two or three of these in a total proportion of at least 0.1 per cent. and not exceeding 5 per cent. is) reheated after casting and solidification to such a temperature, e.g. 1200-1300‹C. that coalescing of the impurities insoluble in a solid state ensues and is then decarbonised by heating in a reducing atmosphere to a temperature closely below the ti-anisitio n point of the alpha-gamma phase of the alloy, e.g. about 950‹C. The reducing atmosphere may be hydrogen saturated with vapour or of producer gas saturated with water vapour. For pieces of 1 mm. thickness the decarbonisation takes at least 1 hour and this time increases proportionally with the square of the thickness. |
