Description

Sphärogusslegierungnodular cast iron
Die Erfindung bezieht sich auf eine Sphärogusslegierung für Gusseisenprodukte mit einem hohen E-Modul, wobei die Sphärogusslegierung als Nicht- Eisenbestandteile zumindest die Elemente C, Si, Mn, Cu, Mg, S und als Beimengungen Ni und/oder Mo enthält.The invention relates to a spheroidal cast iron alloy for cast iron products with a high modulus of elasticity, the spheroidal cast iron alloy containing at least the elements C, Si, Mn, Cu, Mg, S and as admixtures Ni and / or Mo as non-iron components.
Im Kraftfahrzeugbau werden Sphärogusslegierungen verwendet für die Herstellung von Gussteilen, die einen hohen Widerstand gegen Torsionsmomente haben müssen, beispielsweise die Kurbelwelle, als Teil des Motors imDuctile iron alloys are used in motor vehicle construction for the production of cast parts which must have a high resistance to torsional moments, for example the crankshaft, as part of the engine in the
Kraftfahrzeug. Die Gussteile haben oft eine sehr komplexe Geometrie mit vielen Bereichen, die unterschiedlich belastet werden und deshalb unterschiedliche Wandstärken aufweisen. Dies setzt eine Giesstechnik voraus, die geeignet ist für Teile mit stark differenzierten Geometrien. Auch müssen die Gussteile oft nachbehandelt werden. Die Nachbehandlung kann eine Wärmebehandlung und/oder eine zerspanende Behandlung sein. Eine wichtige Eigenschaft, die für solchen Gussteile gewünscht wird, ist ein E-Modul, der möglichst hoch ist. Üblicherweise werden derzeit Legierungen mit einem E-Modul von bis zu ca. 160 GPa verwendet. Für Teile mit einem möglichst hohen E-Modul wird man üblicherweise eine Stahllegierung verwenden und die Teile anschliessend durch Schmieden bearbeiten. Diese Herstellungsmethode ist jedoch kostspielig.Motor vehicle. The castings often have a very complex geometry with many areas that are subjected to different loads and therefore have different wall thicknesses. This requires a casting technique that is suitable for parts with highly differentiated geometries. The castings also often have to be post-treated. The aftertreatment can be a heat treatment and / or a machining treatment. An important property that is desired for such cast parts is an elastic modulus that is as high as possible. Alloys with a modulus of elasticity of up to approx. 160 GPa are currently usually used. A steel alloy is usually used for parts with the highest possible modulus of elasticity and the parts are then machined by forging. However, this manufacturing method is expensive.
Aus der WO 99/19525 ist eine Sphärogusslegierung bekannt, die für Wellen und Scheiben einer Scheibenbremse verwendet werden kann. Die Legierung enthält in Gewichtsprozent 1.5 bis 4.5 % C, 1.5 bis 4.5 % Si und mindestens 1.0 bis 6.5 % Mo, sowie eventuell Ni und Cu, wobei die Summe (% Mo + % Ni + % Cu) 6.5% nicht übersteigt, und als Rest Eisen und den üblichen Verunreinigungen. Die Legierung zeichnet sich aus durch eine gute Beständigkeit gegen hohe Temperaturen und Abrieb.WO 99/19525 discloses a nodular cast iron alloy which can be used for shafts and disks of a disc brake. The alloy contains in percent by weight 1.5 to 4.5% C, 1.5 to 4.5% Si and at least 1.0 to 6.5% Mo, and possibly Ni and Cu, the sum (% Mo +% Ni +% Cu) not exceeding 6.5%, and as Balance iron and the usual impurities. The alloy is characterized by good resistance to high temperatures and abrasion.
Aus der WO 96/38596 ist eine Sphärogusslegierung mit hohem E-Modul bekannt. Die Legierung enthält in Gewichtsprozent: 3.0 bis 3.8 % C, 2.0 bis 2.6 % Si, 0.2 bis 0.6 % Mangan, weniger als 0.02 % P, weniger als 0.03 % S, 0.03 bis 0.06% Magnesium, 0.8 bis 1.2 % Ni, 0.8 bis 1.2 % Cu, 0.4 bis 1.0% Mo und als Rest Fe.WO 96/38596 discloses a spheroidal cast iron alloy with a high modulus of elasticity.

Bekannt sind Sphärogusslegierungen mit hohen Perlit- und Graphitanteilen. Bei diesen bekannten Legierungen ist der E-Modul für gewisse Anwendungen zu niedrig. Wenn der Graphitgehalt tief gehalten wird, wird der Matrixanteil grösser und der E-Modul höher. Es entsteht mehr Mischkristall als Graphit. .Ductile iron alloys with high pearlite and graphite contents are known. With these known alloys, the modulus of elasticity is too low for certain applications. If the graphite content is kept low, the matrix portion becomes larger and the modulus of elasticity higher. There is more mixed crystal than graphite. ,
Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, eine Sphärogusslegierung für Gusseisenprodukte mit einem E-Modul höher als 170 GPa anzugeben.Starting from this prior art, it is an object of the invention to provide a spheroidal cast iron alloy for cast iron products with a modulus of elasticity higher than 170 GPa.
Diese Aufgabe wird dadurch gelöst, dass die Legierung zusammengesetzt ist aus Gewichtsprozenten: C < 2.9 %, Si 3.8 bis 4.3 %, Cu 0.5 bis 1.0 %, Ni und/oder Mo 0 bis 4 %, Mn 0.1 bis 0.8 %, Mg 0.03 bis 0.07 % und S maximal 0.015 %, wobei die Mischungsanteile C und Si sehr nahe beim Eutektikum liegen.This object is achieved in that the alloy is composed of percentages by weight: C <2.9%, Si 3.8 to 4.3%, Cu 0.5 to 1.0%, Ni and / or Mo 0 to 4%, Mn 0.1 to 0.8%, Mg 0.03 to 0.07% and S at most 0.015%, whereby the mixture proportions C and Si are very close to the eutectic.
Bevorzugte Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.Preferred developments of the invention result from the dependent claims.
Es ist von Vorteil, dass der Perlitanteil im Gefüge der Gusseisenprodukte reduziert wird und die Legierung sehr nahe ans Eutektikum kommt. Dies wird dadurch erreicht, dass der Perlitanteil weniger als 50 bis 70 % beträgt. Durch den tieferen Perlitanteil werden die Zerspanungseigenschaften verbessert.It is advantageous that the pearlite content in the structure of the cast iron products is reduced and that the alloy comes very close to the eutectic. This is achieved in that the pearlite content is less than 50 to 70%. The cutting properties are improved by the lower percentage of pearlite.
Es ist auch von Vorteil, dass im Gefüge der Gusseisenprodukte eine Verfestigung der Mischkristalle gewährleistet werden kann. Dies wird dadurch erreicht, dass der Si-Gehalt 3.8 bis 4.0 % beträgt.It is also advantageous that solidification of the mixed crystals can be ensured in the structure of the cast iron products. This is achieved by the Si content being 3.8 to 4.0%.
Der Kemgedanke der Erfindung ist es, eine Sphärogusslegierung anzugeben, die besonders geeignet ist für Kurbelwellen in Verbrennungsmotoren. Durch den höheren E-Modul wird die Bruchgefahr, auch bei einer einteiligen Welle mit einer Geometrie mit abwechslungsweise verhältnismässig geringen und grossen Querschnitten erheblich reduziert und die Lebensdauer der Welle erheblich verlängert. Auch die Steifigkeit der Kurbelwelle wird erhöht. Hierdurch wird eine bessere Laufruhe der Kurbelwelle erreicht. Eine bessere Laufruhe bedeutet auch, dass die Erschütterungen, die auf die Lager der Kurbelwelle einwirken, erheblich reduziert werden. Die Lager und die Welle erreichen dadurch eine deutlich längere Betriebslebensdauer. Der C-Gehalt ist massgebend für den E- Modul der Kurbelwelle. Wenn der Graphitanteil in der Legierung tief gehalten wird, wird der volumetrische Anteil der Mischkristalle im Vergleich zum Graphitanteil im Gefüge grösser. Hierdurch steigt der E-Modul. Sphärogusslegierungen mit C-Gehalten unterhalb 3.0 % sind bisher nicht bekannt. Üblicherweise enthalten Sphärogusslegierungen 10 bis 15 Vol. % Graphit. Mit der hier vorgeschlagenen Sphärogusslegierung wird erstmals einen Graphitanteil von maximal 10 Vol. % angestrebt.The core idea of the invention is to provide a spheroidal cast iron alloy which is particularly suitable for crankshafts in internal combustion engines. The higher modulus of elasticity considerably reduces the risk of breakage, even in the case of a one-piece shaft with a geometry with alternately relatively small and large cross sections, and the life of the shaft is considerably extended. The rigidity of the crankshaft is also increased. As a result, the crankshaft runs more smoothly. Better smoothness also means that the vibrations that act on the bearings of the crankshaft are significantly reduced. As a result, the bearings and the shaft achieve a significantly longer service life. The C content is decisive for the modulus of elasticity of the crankshaft. If the graphite content in the alloy is kept low, the volumetric proportion of the mixed crystals increases in comparison to the graphite content in the structure. This increases the modulus of elasticity. Nodular cast iron alloys with C contents below 3.0% are not yet known. Ductile iron alloys usually contain 10 to 15% by volume of graphite. With the nodular cast alloy proposed here, a graphite content of a maximum of 10 vol.
