Title: Improvements in the manufacture and production of iron having special magnetic properties
IPC: C22B5/20
Filed: 1930-01-30
Abstract: Iron having good magnetic properties is made by subjecting iron which has been obtained from finely divided iron by sintering, and the application of pressure, or heat, or both, preferably in an atmosphere of hydrogen, to a heat treatment in vacuo below its melting point, above 400 DEG  C., and preferably between 600-900 DEG C., their treatment being repeated if necessary.  Iron powder obtained from iron carbonyl, or from iron chloride, is suitable. Prior to the heat treatment, the iron may be worked in the cold by rolling or stretching, the initial permeability increasing with the size of the grains.  In an example, iron powder produced from iron carbonyl and containing 1,2 per cent of carbon and of oxygen, is sintered, decarbonized, and reduced at 650 DEG  C. in hydrogen.  The material is further heated to 1100 DEG  C. in hydrogen, and is rolled into sheets one millimetre thick, which are glowed in hydrogen, rolled while cold to ,5 mm., and then glowed at 850 DEG  C. for 24 hours in vacuo.  The resulting sheets have an initial permeability of 1000, maximum permeability of 14500, coercive force of ,19 gauss and remanence of 5200.
