Description
<Desc/Clms Page number 1>
AusscheidungshärtendeLegierungen.
EMI1.1
Legierungen mit niedrigerem Kohlenstoffgehalt auch hinsichtlich ihrer Schnittleistungen wesentlich überlegen.
Als Beispiel einer Legierung nach der Erfindung wird folgende Zusammensetzung angegeben :
EMI1.2
Die Wärmebehandlung dieser Legierung besteht in einem Abschrecken (z. B. von etwa 1150-1350'C) mit nachfolgendem AnlAssen auf etwa 400-800 C (z. B. auf etwa 650''C). Das Abschrecken und Anlassen kann auch durch eine langsame Abkühlung ersetzt werden. Diese Legierung bat in besonders hohem Masse die Fähigkeit, ihre Eigenschaften, z. B. Härte, Schneidfähigkeit und magnetische Eigenschaften, auch bei höheren Temperaturen beizubehalten. Sie ist daher hervorragend zur Herstellung von Gegenständen (z. B. Schneidwerkzeugen, Warmwerkzeugen, Federn.
Magneten) geeignet, die bei höheren Temperaturen beansprucht werden oder sich durch die Beanspruchung erwärmen.
PATENT-ANSPRACHE :
1. Ausscheidungshärtende Legierungen, die neben Eisen etwa 10-30% Wolfram und 2-12% Molybdän, einzeln oder zusammen, sowie 3-50% (vorteilhaft 25-50%) Kobalt enthalten, zur Herstellung von Gegenständen (z. B. Schneidwerkzeugen, Warmarbeitswerkzeugen, Federn, Magneten), die bei höheren Temperaturen beansprucht werden oder sich durch die Beanspruchung erwärmen, dadurch gekennzeichnet, dass sie bei einem zwischen 0'1-0'55% gelegenen Kohlenstoffgehalt ausserdem bis 10% mindestens eines Elementes (z. B.
Vanadium, Titan, Tantal) enthalten, das eine grössere Verwandtschaft zum Kohlenstoff besitzt als Wolfram und Molybdän.

Precipitation hardening alloys.
EMI1.1
Alloys with a lower carbon content are also significantly superior in terms of their cutting performance.
The following composition is given as an example of an alloy according to the invention:
EMI1.2
The heat treatment of this alloy consists of quenching (e.g. from about 1150-1350 ° C) with subsequent annealing to about 400-800 ° C (e.g. to about 650 ° C). Quenching and tempering can also be replaced by slow cooling. This alloy had the ability to improve its properties, e.g. B. hardness, cutting ability and magnetic properties to be maintained even at higher temperatures. It is therefore excellent for the manufacture of objects (e.g. cutting tools, hot tools, springs.
Magnets), which are stressed at higher temperatures or heat up due to the stress.
PATENT APPROACH:
1. Precipitation-hardening alloys, which in addition to iron contain about 10-30% tungsten and 2-12% molybdenum, individually or together, and 3-50% (advantageously 25-50%) cobalt, for the production of objects (e.g. cutting tools , Hot working tools, springs, magnets) which are stressed at higher temperatures or heat up due to the stress, characterized in that with a carbon content between 0.1-0.55% they also contain up to 10% of at least one element (e.g. .
Vanadium, titanium, tantalum), which are more closely related to carbon than tungsten and molybdenum.
