Description
Glühen von Eisen -Aluminium -Legierungen Im Patent 908 736 ist ein Verfahren zur Verbesserung der Anfangspermeabilität von Eisen-Silizium-Legierungen mit bis zu 6% Silizium durch eine Wärmebehandlung bei vorzugsweise goo bis 130o° C in einer Wasserstoffatmosphäre geschützt, welches dadurch gekennzeichnet ist, daß die Wärmebehandlung in einer reinen Wasserstoffatmosphäre mit weniger als o,1 % Stickstoffgehalt durchgeführt wird und die reine Wasserstoffatmosphäre außerdem gegebenenfalls weniger als o,oi g Wasser pro cbm aufweist.Annealing of iron-aluminum alloys In the patent 908 736 a method for improving the initial permeability of iron-silicon alloys with up to 6% silicon is protected by a heat treatment at preferably goo up to 130o ° C in a hydrogen atmosphere, which is characterized by that the heat treatment is carried out in a pure hydrogen atmosphere with less than 0.1% nitrogen content and the pure hydrogen atmosphere also optionally has less than 0.1 g of water per cubic meter.
Es wurde gefunden, cdaß dieses Verfahren sich mit Vorteil auch zum Glühen von Eisen-Aluminium-Legierungen mit bis- zu 6% Aluminium und von Eisen-Silizium-Legierungen mit insgesamt bis zu 6'% Aluminium und Silizium anwenden läßt. Auch bei diesien Legierungen wird durch das Glühverfahren gemäß dem Hauptpatent die Anfangsperm,eabilität verbessert.It has been found that this method can also be used to advantage Annealing of iron-aluminum alloys with up to 6% aluminum and of iron-silicon alloys with a total of up to 6% aluminum and silicon can be used. Even with this one Alloys are given the initial permeability by the annealing process according to the main patent improved.
