Description

Es ist bereits vorgeschlagen, ,gehört aber noch nicht zum Stande,der Technik, magnetische Leiter mit temperaturabhängiger Änderung der Magnetisierungsintensität aus Legierungen herzustellen, die 3o bis 70% Nickel, 5 bis 25 0/0 Chrom und. als Rest Eisen mit Verunreinigungen enthalten.It has already been proposed, but is not yet part of the state Technology, magnetic conductors with temperature-dependent change in magnetization intensity from alloys containing 3o to 70% nickel, 5 to 25 0/0 chromium and. as Remainder containing iron with impurities.

Für den angegebenen Verwendungszweck sind solche Legierungen die ,geeignetsten, die in einem großen Bereich unterhalb des Curiepunktes einen möglichst linearen Verlauf der Temperaturmagnetisierungskurve aufweisen. Ein solcher Verlauf der Temperaturmagnetisierungskurve wird; nach der Erfindung in. einem sehr großen Temperaturbereich erhalten, wenn der magnetische Leiter aus einer Legierung besteht, die o bis 0,5'/o Kohlenstoff, o bis 0,7% Silizium, o bis i % Mangan, 3o bis 50% Nickel, 3 bis 150/0- Chrom, o bis 50/e Molybdän, Rest Eisen und etwaige Verunreinigungen enthält und nach einer Glühung bei Temperaturen von mehr als 80o° C schnell abgekühlt und bei Temperaturen zwischen 400 und 80o° C angelassen wird. Vor dem Anlassen kann auch noch eine Verformung erfolgen.For the stated purpose, such alloys are the most suitable which is as linear as possible in a large area below the Curie point Have the course of the temperature magnetization curve. Such a course of the temperature magnetization curve will; obtained according to the invention in. A very large temperature range, if the magnetic conductor is made of an alloy containing 0 to 0.5% carbon, o to 0.7% silicon, o to i% manganese, 3o to 50% nickel, 3 to 150/0 chromium, o contains up to 50 / e molybdenum, the remainder iron and any impurities and after one Annealing at temperatures of more than 80o ° C and rapidly cooled at temperatures is tempered between 400 and 80o ° C. A deformation can also occur before starting take place.

In der Zeichnung ist die Temperaturmagnetisierungskurve. einer Legierung mit 0;1i5 % Kohlenstoff, 0,58 °/o Silizium, o,iS%a Mangan, 35 % Nickel, 6,q.0/0 Chrom, 0,59% Molybdän, Rest Eisen, dargestellt. Die Kurve wurde an einer Probe dieser Legierung ermittelt, die bei einer Stärke von 7 mm während io.Minuten bei iooö°C geglüht, in Wasser abgekühlt, auf eine Stärke von o,5 mm kaltgewalzt und 1/2 Stunde bei 700° C mit nachfolgender Luftabkühlung angelassen, worden war. Wie die Kurve zeigt, ist die Legierung in einem außergewöhnlich großen Temperaturbereich als Temperaturausgleichswerkstoff verwendbar. Dieser Temperaturbereich hat durch die angegebene Wärmebehandlung eine wesentliche Erweiterung erfahren.In the drawing is the temperature magnetization curve. an alloy with 0.15% carbon, 0.58% silicon, 0.1% a manganese, 35% nickel, 6, q.0 / 0 Chromium, 0.59% molybdenum, remainder iron. The curve was made on a sample of this Alloy determined, which at a thickness of 7 mm for 10 minutes at 100 ° C Annealed, cooled in water, cold-rolled to a thickness of 0.5 mm and 1/2 hour annealed at 700 ° C with subsequent air cooling. Like the curve shows, the alloy is in an exceptionally wide temperature range as a temperature compensation material usable. Due to the specified heat treatment, this temperature range has a experience significant expansion.
