Description

Geschoß Die zum Durchschlagen von Panzerplatten benutzten Geschosse für Gewehre, Maschinengewehre, Tankabwehrgewehre u. dgl., die sogenannte SMK-Munition, besitzen bekanntlich einen Kern aus hochlegiertem Wolframstahl, der unter Zwischenfügung einer Weicheisenschickt von einem Chromnickelstahlmantel umschlossen ist.Bullet The bullets used to penetrate armor plates for rifles, machine guns, anti-tank rifles and the like, the so-called SMK ammunition, are known to have a core made of high-alloy tungsten steel, which is interposed a soft iron is enclosed by a chrome-nickel steel jacket.

Erfindungsgemäß wurde erkannt, däß eine weit höhere Durchschlagskraft derartiger Geschosse erzielt werden kann, wenn der Kern aus einer an sich bekannten Legierung von Wolframcarbid mit etwa 3 bis 7 % Kohlenstoffgehalt und leichter schmelzenden Hilfsmetallen, wie insbesondere Kobalt, Eisen öder Nickel, in Mengen bis höchstens 2o % besteht.According to the invention it was recognized that a much higher penetration power of such projectiles can be achieved if the core is made of a known alloy of tungsten carbide with about 3 to 7 % carbon content and more easily melting auxiliary metals, such as cobalt, iron or nickel, in amounts up to at most 2o % exists.

Es ist zwar bereits bekannt, zur Herstellung von Geschossen Legierungen aus Wolfram, Kohlenstoff, Eisen und Nickel zu verwenden. Hierbei bildeten jedoch das Eisen und das Nickel den Hauptbestandteil; der Kohlenstoffgehalt war außerdem so gering, daß nur ein kleiner Teil des nür zusätzlich verwendeten Wolframs in ein Carbid übergeführt wurde. Um derartige in ihrer Zusammensetzung wesentlich abweirh,ende Legierungen für Gescheßzwecke geeignet zu machen, mußten sie zudem nachträglich geschmiedet und auch einer Wärmebehandlung unterworfen werden.It is already known for the production of projectiles alloys made of tungsten, carbon, iron and nickel to be used. Here, however, formed the iron and nickel are the main constituents; the carbon content was also so small that only a small part of the additional tungsten used in one Carbide was transferred. In order to diverge significantly in their composition, end To make alloys suitable for business purposes, they also had to be retrospectively forged and also subjected to heat treatment.

Die erfindungsgemäß verwendete Legierung besitzt dagegen durch die 8o °/A der gesamten Legierung übersteigende große Menge des Wolframcarbides, das zweckmäßig in Form des einen Kohlenstoffgehalt von 6,12 % besitzenden Wolf rammonocarbides benutzt wird, eine unvergleichlich viel größere diamantähnliche Härte und trotzdem eine durch- den Hilfsmetallgehalt hervorgerufene grol3eFestigkeit, so daß sie schon allein wegen dieser beiden Eigenschaften für die Herstellung von Geschossen weit besser geeignet ist. Dazu kommt aber noch, daß die Legierung durch ihren großen Gehalt an Wolframcarbid auch ein sehr hohes spezifisches Gewicht besitzt, was bekanntlich für die Flugbahn des Geschosses günstig ist.The alloy used according to the invention, on the other hand, has the 8o ° / A of the entire alloy exceeding a large amount of tungsten carbide that expediently in the form of a carbon content of 6.12% owning Wolf rammonocarbides is used, an incomparably much greater diamond-like hardness and yet a high strength brought about by the auxiliary metal content, so that it already Because of these two properties alone, it is widely used in the manufacture of projectiles is more suitable. But there is also the fact that the alloy has a large Tungsten carbide content also has a very high specific weight, which is known is favorable for the trajectory of the projectile.

Die als Kern verwendete Legierung wird zweckmäßig durch Pressen und Sintern eines Gemisches von pulverförmigem Wolframcarbid und pulverförmigem Hilfsmetall gebildet. Es kann aber natürlich auch von einem Pulvergemisch aus Wolfram, Kohlenstoff und Hilfsmetall ausgegangen werden. Das Pressen und Sintern kann ebensowohl nacheinander als auch gleichzeitig erfolgen. Der Anteil der Hilfsmetalle beträgt zweckmäßig etwa 5 bis 1o °/o des die Grundmasse bildenden Wolframcarbides.The alloy used as the core is conveniently made by pressing and Sintering a mixture of powdery tungsten carbide and powdery auxiliary metal educated. Of course, it can also consist of a powder mixture of tungsten and carbon and auxiliary metal are assumed. The pressing and sintering can as well be one after the other as well as at the same time. The proportion of auxiliary metals is expediently about 5 to 10 per cent of the tungsten carbide forming the matrix.

Die Erfindung läßt sich auch nutzbringend bei Geschoßköpfen für Granaten verwenden.The invention can also be useful with projectile heads for grenades use.
