Definitions
- the method of producing a magnetic material of high permeability and low hys- 'teresis action which consists in alloying a magnetic substance with silicon, heating said substance to a tem erature below its meltingoint, mechanical y treating said substance to reduce it to a sheet, reheating said sheet to a temperature below its melting-point, and different and finally-cooling.

METHOD'OF MAKING NIAGNEITIC MATERIALS.
- Specification of Letters Patent; Application fi1ed Ju1y-5, 1908. Serial No. 324,897,
' Patented Nov. 2-7 1906.
Too/ll whom it may concern:
Be it known that I, ROBERT ABBOTT HA FIELD, a subject of the King of Great Britain,
residing at Sheffield, England, have invented 1 Improvement in of a certain new and use Methods of Making Magnetic Materials,
I which the following is a specification.-
In United States Letters Patent No.-
767,110, granted to me August 9, 1904, I' have descr'bed and claimed a method of p said alloy is really heated three times-that is to say, once before mechanical treatment and twice afterward.
In carrying my present process into effect I eliminate one of these subsequent heat treatments, or rather substitute for it the preliminary heating before mechanicaltreat- Thus I first heat the material to, say,
treated, and hence the it or otherwise mechanically reduce it to a thin sheet, then reheat to between-900 and 1,000 centigrade, and finally cool.
'1'. The method of producing a magnetic material of high permeability and low hys- 'teresis action, which consists in alloying a magnetic substance with silicon, heating said substance to a tem erature below its meltingoint, mechanical y treating said substance to reduce it to a sheet, reheating said sheet to a temperature below its melting-point, and different and finally-cooling.
2. The method of producing a magnetic from said first-named temperature,
material of high permeability andlow hysteresis action, which magnetic substance with silicon, heating said substance to a temperature below its melting-point, mechanically treating said subconsists in alloying'a stance to reduce -it to a sheet, reheating said ,sheet to a temperature below its meltingpoint but above said first-named temperature, and finally coolin In witness whereof I have signed my name hereto in the presence of two witnesses;
ROBERT A. HADFIELD.
