Description
Legierter Sinterstahl. Legierte Stähle, wie sie in bekannter Weise durch Giessen hergestellt werden, haben seit vielen Jahren für die verschie densten Zwecke in der gesamten Technik eine sehr bedeutende Verwendung gefunden. Obwohl man durch mannigfache Auswahl der Legierungskomponenten oftmals Stahl legierungen mit spezifischen Eigenschaften erhalten konnte, war dennoch die Herstellung derselben infolge zu geringer oder gänzlich fehlender Legierungsbildung einzelner Kom ponenten in vielen Fällen beschränkt.
Erst als die Methoden der Pulvermetal lurgie für die Herstellung legierter Stähle nutzbar gemacht wurden, hatte man einen Weg gefunden, legierte Sinterstähle zu erzeu gen, wie sie durch Giessen vielfach nicht er reicht werden konnten.
Die Erfindung betrifft nun einen legierten Sinterstahl, der 0,2 bis 2,5% Kohlenstoff, 1 bis 20% Mangan und 7,5 bis 30% Kupfer enthält. Zwecks Erzielung besonderer Eigen schaften, z. B. erhöhter Korrosions- und Warmfestigkeit, können die Legierungen bis zu 30% Chrom, bis zu 20% Nickel,
Kobalt oder Wolfram sowie gegebenenfalls in Men gen bis zu 5% mindestens ein Metall der dritten bis fünften Gruppe des periodischen Systems der Elemente, wie Vanadin, Niob, Tantal, Titan, Zirkonium oder Aluminium, eventuell auch bis zu 5% Molybdän oder Bor, einzeln oder zu mehreren, enthalten, wobei jedoch der Gesamtgehalt der mit dem Eisen und Kohlenstoff legierten Stoffe 50% nicht überschreiten darf.
Die erfindungsgemässen legierten Sinter- stähle können nach den bekannten Methoden der Pulvermetallurgie hergestellt werden. So können z. B. die Pulver der einzelnen Legie rungsbestandteile mit Eisenpulver gemischt, gepresst und anschliessend gesintert werden.
Als zweckmässig hat es sich gezeigt, gepul- verte Vorlegierungen aus zwei oder drei Le gierungsmetallen, beispielsweise aus Kupfer- Aluminium, Kupfer-Mangan, Kupfer-Eisen- Mangan, Kupfer-Mangan-Kohlenstoff, Kup- fer-Chrom-Kohlenstoff oder Kupfer-Alumi- nium-Mangan zu verwenden.
In besonders bevorzugter Weise kann die Kupferkom ponente - gegebenenfalls auch als Vorlegie- rung - dem aus den übrigen Komponenten gepressten und gesinterten Formstück durch Tränken einverleibt werden. Die verschie denen Verfahren können auch kombiniert werden. So kann man z.
B. die Kupferkom ponente zum Teil in Pulverform dem Aus gangspulver zumischen und den Rest des Kupfers in das gepresste und gesinterte Formstück durch Tränken einbringen.
Die erhaltenen Stähle können in bekann ter Weise nachbehandelt werden. So sind z. B. durch Abschrecken und Anlassen Aus scheidungshärtungseffekte in der Grund masse und auch in der Kupferphase zu erzie len. Der Kohlenstoff kann auch in bekannter Weise durch Einsatzhärtung eingebracht werden.
Gegenüber den geschmolzenen Man ganstählen zeigen die erfindungsgemässen legierten Sinterstähle eine ausserordentlich hohe Härte sowie ausgezeichnete Festigkei- ten und Dehnungen und sind daher überall dort bevorzugt anzuwenden, wo es auf diese Eigenschaften und besonders hohe Ver- schleissfestigkeiten ankommt.
Gegenüber den bisher bekanntgewordenen gesinterten reinen Manganstählen, die stets eine gewisse Poro- sität aufweisen, können die Legierungen nach der Erfindung infolge eines dichteren Gefüges von wesentlich gesteigerter Härte und Festigkeit sein.
<I>Beispiel 1:</I> Martensitischer, kupfergetränkter Man gansinterstahl: Kohlenstoff 0,8% Mangan 6% Kupfer 10% Eisen Rest Dieser Sinterstahl zeigt eine Vickershärte von 840 kg/mm2. Derselbe Sinterstahl, jedoch ohne Kupfergehalt, zeigt eine Vickershärte von 290 kg/mm2, während geschmolzener Stahl ohne Kupfergehalt eine Vickershärte von 400 kg/mm:2 aufweist.
<I>Beispiel 2:</I> Austenitischer, kupfergetränkter Man gansinterstahl Kohlenstoff 0,8% Mangan 14 Kupfer 13 Eisen Rest Dieser Sinterstahl zeigt eine Vickershärte von 350 kg/mm2. Derselbe Sinterstahl, jedoch ohne Kupfergehalt, zeigt eine Vickershärte von 170 kg/mm@. Der gleiche geschmolzene Stahl ohne Kupfergehalt weist eine Vickers- härte von 200 kg/mm2 auf.
<I>Beispiel 3:</I> Chrom-Mangan-Sinterstahl Kohlenstoff 0;2 /a Mangan 7,50/, 1 Chrom 15% Kupfer 25% Aluminium 2 Dieser nichtrostende Sinterstahl hat eine Vickershärte von 400 kg/mm2. Derselbe Sin- terstahl ohne Kupfer zeigt eine Vickershärte von 145 kg/mm2. Der gleiche Gussstahl ohne Kupfer weist eine Vickershärte von 220 kg/mm2 auf.
Beispiel <I>4:</I> Nickel-Chrom-Mangan-Sinterstahl Kohlenstoff 0,3% Mangan 4% Chrom 8% Nickel 15% Kupfer 15 Eisen Rest Eigenschaften ähnlich wie in Beispiel 3, aber korrosionsfester.
Alloy sintered steel. Alloy steels, as they are produced in a known manner by casting, have found a very important use for many years for the most diverse purposes in the entire technology. Although it was often possible to obtain steel alloys with specific properties through a diverse selection of alloy components, the production of the same was in many cases limited due to insufficient or complete lack of alloying of individual components.
It was only when the methods of powder metallurgy were made usable for the production of alloyed steels that a way was found to produce alloyed sintered steels, which in many cases could not be achieved by casting.
The invention now relates to an alloyed sintered steel which contains 0.2 to 2.5% carbon, 1 to 20% manganese and 7.5 to 30% copper. In order to achieve special properties such. B. increased corrosion and heat resistance, the alloys can contain up to 30% chromium, up to 20% nickel,
Cobalt or tungsten and optionally in quantities of up to 5% at least one metal from the third to fifth group of the periodic system of elements, such as vanadium, niobium, tantalum, titanium, zirconium or aluminum, possibly also up to 5% molybdenum or boron, individually or several, but the total content of the substances alloyed with the iron and carbon must not exceed 50%.
The alloyed sintered steels according to the invention can be produced by the known methods of powder metallurgy. So z. B. the powder of the individual alloy constituents are mixed with iron powder, pressed and then sintered.
It has been shown to be useful to use powdered master alloys of two or three alloy metals, for example of copper-aluminum, copper-manganese, copper-iron-manganese, copper-manganese-carbon, copper-chromium-carbon or copper Use aluminum manganese.
In a particularly preferred manner, the copper component - optionally also as a pre-alloy - can be incorporated by impregnation into the molded piece pressed and sintered from the other components. The various methods can also be combined. So you can z.
B. mix the Kupferkom component partly in powder form from the starting powder and bring the rest of the copper into the pressed and sintered molding by soaking.
The steels obtained can be post-treated in a known manner. So are z. B. by quenching and tempering excretion hardening effects in the base mass and also in the copper phase to erzie sources. The carbon can also be introduced in a known manner by case hardening.
Compared to the molten manganese steels, the alloyed sintered steels according to the invention show an extraordinarily high hardness as well as excellent strengths and elongations and are therefore preferably used wherever these properties and particularly high wear resistance are important.
Compared to the previously known sintered pure manganese steels, which always have a certain porosity, the alloys according to the invention can be of significantly increased hardness and strength as a result of a denser structure.
<I> Example 1: </I> Martensitic, copper-soaked man-sintered steel: carbon 0.8% manganese 6% copper 10% iron remainder This sintered steel has a Vickers hardness of 840 kg / mm2. The same sintered steel, but without copper content, shows a Vickers hardness of 290 kg / mm2, while molten steel without copper content has a Vickers hardness of 400 kg / mm: 2.
<I> Example 2: </I> Austenitic, copper-impregnated man-sintered steel carbon 0.8% manganese 14 copper 13 iron remainder This sintered steel has a Vickers hardness of 350 kg / mm2. The same sintered steel, but without copper content, shows a Vickers hardness of 170 kg / mm @. The same molten steel without copper content has a Vickers hardness of 200 kg / mm2.
<I> Example 3: </I> Chrome-manganese sintered steel carbon 0; 2 / a manganese 7.50 /, 1 chromium 15% copper 25% aluminum 2 This stainless sintered steel has a Vickers hardness of 400 kg / mm2. The same sintered steel without copper shows a Vickers hardness of 145 kg / mm2. The same cast steel without copper has a Vickers hardness of 220 kg / mm2.
Example <I> 4: </I> nickel-chromium-manganese sintered steel carbon 0.3% manganese 4% chromium 8% nickel 15% copper 15 iron remainder Properties similar to example 3, but more corrosion-resistant.
