Ausscheidungshärtbare Eisenlegierungen., insbesondere zur Herstellung von Warmwerkzeugen.
EMI1.1
ausscheidungshärtbare Eisenlegierungen, die O'l bis 0-4% Kohlenstoff. 10 bis 35"o Wolfram, das ganz oder teilweise durch Molybdän ersetzt sein kann. und bis 10% mindestens eines der Elemente Titan,
Vanadium, Tantal enthalten, das eine grössere Verwandtschaft zum Kohlenstoff besitzt als Wolfram.
Der Zusatz des Kohlenstoffes und des den Kohlenstoff bindenden Elementes bewirkt eine solche Ver- feinerung des Gefüges, dass diese Legierungen eine genügende Zähigkeit besitzen. Ausserdem ist die Her- stellung der kohlenstoffhaltigen Legierungen sehmelzteclmiselh wesentlich einfacher als die kohlenstofffreier Legierungen. Die Legierungen nach der Erfindung zeichnen sich ferner durch eine sehr gute
Schmiedbarkeit aus.
Als Ausführungsbeispiel des Erfindungsgegenstandes sei eine Legierung angegeben, die neben
EMI1.2
Diese Legierung zeigte nach dem Abschrecken von 1200 0 C in Wasser eine Härte von 302 Brinelleinheiten, die nach dem Anlassen bei 7500 C auf 477 BrineIleinheiten stieg.
EMI1.3
Gehalt an Titan, Vanadium oder Tantal gehalten werden. Die Abbindung des Kohlenstoffes ist erreicht, wenn der Vanadiumgehalt etwa das ssfache, der Titangehalt etwa das 4fache und der Tantalgehalt etwa
EMI1.4
nach der Erfindung bekanntermassen ganz oder teilweise durch Molybdän ersetzt werden.
Die Wärmebehandlung der Legierungen besteht zweckmässig in einer schnellen Abkühlung von einer Temperatur oberhalb 950 C und nachfolgendem Anlassen auf etwa 400 bis 8500 C.
Die Legierungen nach der Erfindung sind insbesondere für die Herstellung von Warmwerkzeugen geeignet, da die bei ihnen erzielbaren Festigkeiten von 140 bis 170 k/mm, die gerade fiirWarmwerkzeuge geeignet sind, beim Anlassen über einen sehr grossen Temperaturbereich erhalten werden, so dass auch die im Gebrauch eintretenden Erhitzungen, selbst wenn sie die Anlasstemperatur überschreiten, keine schädliche Herabsetzung der Festigkeit und damit verbundene Volumenänderungen mit Spannungen
EMI1.5
überhaupt keine höheren Festigkeiten annehmen als für Warmwerkzeuge praktisch in Frage kommen.
Sie besitzen ausserdem eine sehr hohe Anlassbeständigkeit.

Precipitation hardenable iron alloys., In particular for the production of hot tools.
EMI1.1
Precipitation hardenable iron alloys containing O'l to 0-4% carbon. 10 to 35 "o tungsten, which can be completely or partially replaced by molybdenum. And up to 10% of at least one of the elements titanium,
Contains vanadium, tantalum, which is more closely related to carbon than tungsten.
The addition of carbon and the element that binds the carbon causes such a refinement of the structure that these alloys have sufficient toughness. In addition, the production of the carbon-containing alloys sehmelzteclmiselh is much easier than the carbon-free alloys. The alloys according to the invention are also characterized by very good properties
Forgeability.
As an exemplary embodiment of the subject matter of the invention, an alloy is specified which, in addition to
EMI1.2
After quenching at 1200 ° C. in water, this alloy showed a hardness of 302 Brine units, which increased to 477 Brine units after tempering at 7500 C.
EMI1.3
Content of titanium, vanadium or tantalum are kept. The setting of the carbon is achieved when the vanadium content is about ssfold, the titanium content about 4 times and the tantalum content about
EMI1.4
according to the invention are known to be wholly or partially replaced by molybdenum.
The heat treatment of the alloys expediently consists of rapid cooling from a temperature above 950 C and subsequent tempering to around 400 to 8500 C.
The alloys according to the invention are particularly suitable for the production of hot tools, since the strengths of 140 to 170 k / mm that can be achieved with them, which are particularly suitable for hot tools, are maintained over a very large temperature range during tempering, so that they are also used Occurring heating, even if it exceeds the tempering temperature, no detrimental reduction in strength and associated volume changes with stresses
EMI1.5
do not assume any higher strengths than are practically possible for hot tools.
They also have a very high resistance to tempering.
