Abstract

The alloy contains iron and, (expressed by weight), 0.5 to 4% B, 0.05 to 1.5% C and 0.5 to 5% Si wherein the Fe percentage has been increased from 5 to 30% by weight and wherein O.1 to 20% by weight of one or several carbide- and/or boride-forming elements have been added, such as Mo, V, Nb, W, Zr, HF, Ta, Ti and Cr, the last mentioned not being present above. In such an alloy, there is no formation or, at the most, little formation of FeB and Fe3C and a good to a very good ductility is provided. This alloy is less expensive because of its increased Fe content and is further provided with a higher resistance to oxidation and corrosion than that of conventional alloys of this type with an extremely reduced Fe content.

Description

Korrosions- und oxydationsbeständige Mehrstofflegierung auf Ni-BasisCorrosion and oxidation resistant multi-component alloy based on Ni
Die Erfindung betrifft eine korrosions- und oxydationsbeständige Mehrstofflegierung auf Ni-Basis mit Fe, B, C und Si, wobei der Gehalt an B 0,5 bis 4, an C 0,05 bis 1,5 und an Si 0,5 bis 5 Ge¬ wichtsprozent der Legierung beträgt.The invention relates to a corrosion and oxidation-resistant multi-component alloy based on Ni with Fe, B, C and Si, the content of B being 0.5 to 4, C 0.05 to 1.5 and Si 0.5 to 5 Weight percent of the alloy.
Bei bekannten Legierungen dieser Art, die eine Korrosions- und Oxydationsbeständigkeit bis ca. 700 C aufweisen, war es notwendig, den Fe-Gehalt sehr gering zu halten und es wurde xr>. der Praxis angestrebt, diesen so weit als möglich abzusenken.In known alloys of this type, which have a corrosion and oxidation resistance up to approx. 700 C, it was necessary to keep the Fe content very low and it became xr>. the aim in practice is to lower it as much as possible.
Dies hatte seinen Grund in der starken Versprödung, die bei sol¬ chen Legierungen schon bei einem Fe-Gehalt von weniger als 5 Ge¬ wichtsprozent auftritt. Mit steigendem Fe-Gehalt bildet sich nämlich insbesondere ein zunehmender Anteil an FeB sowie auch Fe..C in der Legierung, wodurch deren Duktilität so weit herabge¬ setzt wird, dass sie für die praktische Anwendung kaum -in Frage kommt. Auch ein Zusatz von Cr bringt diesbezüglich keine nennens¬ werte Verbesserung.The reason for this was the strong embrittlement, which occurs with such alloys with an Fe content of less than 5 percent by weight. With increasing Fe content, an increasing proportion of FeB and also Fe..C is formed in the alloy, whereby its ductility is reduced to such an extent that it can hardly be considered for practical use. An addition of Cr does not bring any significant improvement in this regard either.
Der Erfindung liegt die Aufgabe zugrunde, einerseits den Gesteh- ungspreis einer Legierung des eingangs genannten Typs zu ver¬ ringern und andererseits deren physikalische Eigenschaften, wie Elastizitätsmodul, Torsions- und Kompressionsmodul, Verschleiss- festigkeit, Korrosionsbeständigkeit und Oxydationsbeständigkeit zu verbessern.The object of the invention is, on the one hand, to reduce the cost price of an alloy of the type mentioned at the beginning and, on the other hand, to improve its physical properties, such as modulus of elasticity, modulus of torsion and compression, resistance to wear, corrosion resistance and oxidation resistance.
Dies wird erfindungsgemass dadurch erreicht, dass der Gehalt derThis is achieved according to the invention in that the content of the
O PIO PI
WIPO Legierung an'Fe 5 bis 30 Gewichtsprozent beträgt und dass sie ferner insgesamt 0,1 bis 20 Gewichtsprozent eines oder mehrerer karbid- und/oder boridbildender Elemente, ausser Cr, enthält.WIPO And the alloy is at 'Fe 5 to 30 weight percent that it further comprises a total of 0.1 to 20 weight percent of one or more carbide and / or boridbildender elements other than Cr, contains.
Es hat sich nämlich gezeigt, dass der Fe-Gehalt der eingangs ge nannten Legierungen wesentlich erhöht werden kann, wenn der Le¬ gierung Zusätze von Elementen beigegeben werden, die als gute Borid- und/oder Karbidbildner bekannt sind, wie insbesondere Mo, V, Nb, W, Zr, Hf, Ta und Ti. Durch die Anwesenheit dieser Zusätz wird die Bildung von FeB und Fe_C weitgehend verhindert, so das eine gute bis sehr gute Duktilitat erzielt wird. Ferner hat sic überraschenderweise ergeben, dass damit auch die genannten phy¬ sikalischen Eigenschaften generell stark verbessert werden, wo¬ bei durch die Wahl der Zusatzelemente und deren quantitatives Verhältnis untereinander und zu den anderen Bestandteilen be¬ stimmte Eigenschaften besonders hervorgehoben werden können.It has been shown that the Fe content of the alloys mentioned at the outset can be increased significantly if additions of elements known as good boride and / or carbide formers, such as in particular Mo, V, are added to the alloy. Nb, W, Zr, Hf, Ta and Ti. The presence of these additives largely prevents the formation of FeB and Fe_C, so that good to very good ductility is achieved. Furthermore, surprisingly, it has been found that the physical properties mentioned are also generally greatly improved, whereby certain properties can be particularly emphasized by the choice of the additional elements and their quantitative relationship with one another and with the other constituents.
Beispielsweise können durch geringe Zusätze von Elementen wie Zr Hf, Ta und Ti besonders duktile, je nach Cr-Gehalt weiche bis mittelharte Legierungen erhalten werden, während durch Elemente wie Cr, W, Mo, V und Nb höhere Karbid- und Boridgehalte und da¬ mit besonders gute Verschleissfestigkeiten erzielbar sind.For example, small additions of elements such as Zr Hf, Ta and Ti can give particularly ductile, depending on the Cr content, soft to medium-hard alloys, while elements such as Cr, W, Mo, V and Nb have higher carbide and boride contents and da¬ can be achieved with particularly good wear resistance.
Der bevorzugte Bereich für den Fe-Gehalt der Legierung liegt zwischen 6 und 22 Gewichtsprozent. Ein hoher Eisengehalt wird einerseits aus wirtschaftlichen Gründen angestrebt, andererseit hat sich gezeigt, dass gerade in diesem Bereich bei immer noch guter Duktilitat eine sehr hohe Korrosions- und Oxydationsbe¬ ständigkeit erreicht werden kann.The preferred range for the Fe content of the alloy is between 6 and 22 percent by weight. On the one hand, a high iron content is sought for economic reasons, on the other hand, it has been shown that in this area in particular, with still good ductility, a very high resistance to corrosion and oxidation can be achieved.
