Description

Verwendung von Eisen-Chrom-Legierungen als Werkstoff für magnetisch beanspruchte Gegenstände Den Gegenstand des Hauptpatents 73I 4o9 bildet die Verwendung von Eisen-Chrom-Legierungen mit mehr als Io %o bis 4o% Chrom als Werkstoff für solche magnetisch beanspruchten Gegenstände, die eine hone Permeahilität und gegebenenfalls, geringe Wirbelstromverluste aufweisen müssen, insbesondere der Hochfrequenztechnik. Diese Eisen-Chrom-Legierungen können nach dem Hauptpatent bis zu Ioo%o Silicium oder Aluminium oder beide zwecks Erhöhung des elektrischen, Widerstandes und Verbesserungen der magnetischen Eigenschaften enthalten. Der Kohlenstoffgehalt wird zweckmäßig unter o,3% und der Mangangelhallt unter 2 % gelhalten. Die Legierungen, nach dem Hauptpatent zeichnen sich durch, hohe Permeabilität, geringe Wirbelstrom- und Hystereseverluste und kleine Koerzitivkräfte aus.Use of iron-chromium alloys as a material for magnetic claimed objects The object of the main patent 73I 409 is the use of iron-chromium alloys with more than 10% to 40% chromium as the material for such Magnetically stressed objects that have a high permeability and possibly, Must have low eddy current losses, especially high-frequency technology. According to the main patent, these iron-chromium alloys can contain up to 100% silicon or aluminum, or both, for purposes of increasing electrical resistance, and improvements the magnetic properties included. The carbon content becomes appropriate below 0.3% and the Mangangelhallt below 2% gel. The alloys, according to the Main patent are characterized by high permeability, low eddy current and hysteresis losses and small coercive forces.

Nach der Erfindung werden den nach dem Hauptpatent verwendeten Legierungen noch 2 bis ioo%o Manigan und o,i bis 5% Zinn einzeln oder zusammen zugesetzt. Es. hat sich gezeigt, daß bei diesen Zusübzen die vorteilhaften Eigenis:ch.aften der Legierungen erhalten bleiben, bzw. sogar noch verbessert werden. Die Angaben des Hauptpatents über die Vervendung, Zusammensetzung und Wärmebehandlung der Legierungen gelten auch für die erfindungsgemäß verwendeten Legierungen.According to the invention, the alloys used according to the main patent 2 to 100% manigan and 0.1 to 5% tin added individually or together. It. it has been shown that with these additions the beneficial properties of Alloys are retained or even improved. the Details of the main patent on the use, composition and heat treatment of the alloys also apply to the alloys used according to the invention.
