  Verfahren zur Herstellung von sehneidhaltigen   Eisen- und Stahllegierungen.   
   Es ist bereits   bekannt, dass durch Ausscheidungshärtung   härtbare Eisen-und Stahllegierungen (z. B. kupferhaltige Eisenlegierungen), wenn sie von hohen Temperaturen, z. B. etwa 700 bis 13000 C, abgekühlt und anschliessend, z. B. bei etwa 250 bis 700  C, angelassen werden,   Härtungserscheinungen,   die sogenannte   Ausscheidungshärtung,   zeigen, die gleichzeitig mit der Verbesserung anderer technisch wichtiger Eigenschaften, z. B. der Festigkeit und der Streckgrenze, verbunden sind. Es sind auch durch   Ausscheidungshärtung   härtbare Schneidlegierungen bekannt, die neben Eisen 2 bis 40% Wolfram oder Molybdän und 2 bis   40%   Kobalt enthalten. Diese Legierungen sollen jedoch kohlenstoffarm bzw. kohlenstofffrei sein. 
   Die vorliegende Erfindung bezweckt, der Technik ein Verfahren an die Hand zu geben, nach dem Eisen-und Stahllegierungen hergestellt werden können, die sich durch eine besonders gute Schneidhaltigkeit auszeichnen und deshalb mit Vorteil als Schneidmetalle zum Drehen, Bohren, Fräsen usw. verwendet werden können. Dieser   Zweck wird erfindungsgemäss dadurch erreicht, dass   man Eisen-oder Stahllegierungen neben mindestens einem Element (z. B. Titan, Kupfer, Wolfram, Molybdän, Bor), das Aus-   scheidungshärtung   hervorrufen kann, sowie 1 bis 25% Kobalt und Vanadium noch   O'l   bis 0'4% Kohlenstoff zusetzt und die so zusammengesetzten Legierungen dem an sich bekannten   Ausscheidungshärte-   verfahren, bestehend im Abschrecken von hohen Temperaturen, z. B. 700 bis 1300  C, und Anlassen, z.
   B. bei 250 bis 7000 C, wobei das Anlassen durch eine besonders langsame Abkühlung ersetzt werden kann, unterwirft. Es werden auf diese Weise Eisen-und Stahllegierungen erzeugt, die trotz ihres verhältnismässig hohen Kohlenstoffgehaltes eine ausgezeichnete Härte und gute Festigkeitseigenschaften bei der   Ausscheidungshärtung   annehmen und die sich gleichzeitig durch eine besonders gute Schneidhaltigkeit auszeichnen. Der zulässige höhere Kohlenstoffgehalt erleichtert die Herstellung der Eisen-und Stahllegierungen und gestattet, die billigeren Ferrolegierungen (z. B. Eisen-Wolfram-Legierungen) mit höherem Kohlenstoffgehalt bei der Herstellung der Eisen-und Stahllegierungen zu verwenden.

 einzeln oder gemischt, enthalten ; ferner Legierungen, die etwa   0'1   bis 25%, am besten 6 bis 15%, Wolfram oder Molybdän, einzeln oder gemischt, und 1 bis 25%, am besten 5 bis   15%,   Kobalt oder Vanadium, einzeln oder gemischt, enthalten. Von Vorteil ist ferner noch ein Zusatz von bis etwa 5% Silizium oder Mangan, da durch diese Elemente, wie für Eisen-Titan-Legierungen mit einem Kohlenstoffgehalt von weniger als 0'1% bereits bekannt ist, die   Ausscheidungshärtung   begünstigt wird, indem bereits bei verhältnis-   mässig   geringen Mengen des jeweiligen die   Ausscheidungshärtung   hervorrufenden Elementes eine beträchtliche Härtesteigerung eintritt.

  Process for the production of iron and steel alloys containing cutting edges.
   It is already known that precipitation hardenable iron and steel alloys (e.g. copper-containing iron alloys) when they are exposed to high temperatures, e.g. B. about 700 to 13000 C, cooled and then, for. B. at about 250 to 700 C, show hardening phenomena, the so-called precipitation hardening, which simultaneously with the improvement of other technically important properties, eg. B. the strength and the yield point are connected. There are also known cutting alloys which can be hardened by precipitation hardening and which, in addition to iron, contain 2 to 40% tungsten or molybdenum and 2 to 40% cobalt. However, these alloys should be low in carbon or carbon-free.
   The purpose of the present invention is to provide technology with a method by which iron and steel alloys can be produced which are distinguished by particularly good edge retention and can therefore be used with advantage as cutting metals for turning, drilling, milling, etc. . According to the invention, this purpose is achieved by using iron or steel alloys in addition to at least one element (e.g. titanium, copper, tungsten, molybdenum, boron) that can cause precipitation hardening, and 1 to 25% cobalt and vanadium as well as O '1 to 0'4% carbon is added and the alloys composed in this way are subjected to the precipitation hardening process known per se, consisting of quenching at high temperatures, e.g. B. 700 to 1300 C, and tempering, e.g.
   B. at 250 to 7000 C, the tempering can be replaced by a particularly slow cooling, subjects. In this way, iron and steel alloys are produced which, despite their relatively high carbon content, have excellent hardness and good strength properties during precipitation hardening and which at the same time are characterized by particularly good edge retention. The permissible higher carbon content facilitates the production of iron and steel alloys and allows the cheaper ferro alloys (for example iron-tungsten alloys) with a higher carbon content to be used in the production of iron and steel alloys.
   As special
 EMI1.1
 individually or mixed, included; furthermore, alloys which contain approximately 0.1 to 25%, preferably 6 to 15%, tungsten or molybdenum, individually or mixed, and 1 to 25%, preferably 5 to 15%, cobalt or vanadium, individually or mixed. It is also advantageous to add up to about 5% silicon or manganese, since these elements, as is already known for iron-titanium alloys with a carbon content of less than 0.1%, promote precipitation hardening by already being relatively small amounts of the respective element causing the precipitation hardening, a considerable increase in hardness occurs.
