Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die modernen Geschosse für Handfeuerwaffen besitzen bekanntlich einen Kern aus einer Hartbleilegirung (Blei mit ca. 2 pCt. Antimon) und einen Mantel aus Stahlkupfer oder Nickelblech.The modern projectiles for handguns are known to have a core a hard lead coating (lead with approx. 2 pCt. antimony) and a steel-copper jacket or nickel sheet.
Vorliegende Erfindung bezweckt nun, die Bemäntelung der Geschosse ganz überflüssig zu machen, indem dieselben aus einer Legirung hergestellt werden, welche viel widerstandsfähiger ist, als alle bisher zur Herstellung von Geschossen Verwendeten Stoffe. Das neue Geschofs wird im Ziele nicht merklich deformirt, wodurch die Eiridringungstiefe vergröfsert wird, trotzdem ist es aber genügend weich, um in die Züge ohne Schaden für den Lauf eintreten zu können; ein Abschmieren findet dabei jedoch nicht statt.The present invention now aims to make the jacketing of the projectiles completely superfluous by making them from an alloy which is much more resistant than any other substance used to manufacture bullets. The new storey is not noticeably deformed in the target, whereby the penetration depth is increased, nevertheless, it is sufficiently soft to enter the trains without damaging the barrel to be able to; however, there is no smearing.
Diese Vortheile werden ' dadurch erreicht, dafs das Geschofs nicht aus Blei, sondern aus Kupfer oder Nickel oder einer Kupfernickellegirung hergestellt wird, welche Metalle oder Legirungen mit einem entsprechend hohen Zusatz von Wolfram legirt werden, so dafs eine schmiedbare Wolframlegirung entsteht. Dadurch erhält das Geschofs nicht nur die erforderliche Festigkeit und Härte, sondern namentlich auch das erforderliche hohe specifische Gewicht.These advantages are achieved by the fact that the projectile is not made of lead but from lead Copper or nickel or a copper-nickel alloy is made, which metals or Alloys are alloyed with a correspondingly high addition of tungsten, so that a malleable tungsten alloy is created. This not only gives the storey what it needs Strength and hardness, but especially the required high specificity Weight.
Da das Wolfram mit den anderen Metallen legirt wird, sondert es sich beim Walzen, Ziehen oder Pressen der Legirung nicht ab, wie bei den Geschossen, die Wolfram nur in einfacher Mischung enthalten. Durch diese letzteren Geschosse wird der Lauf rasch abgenutzt, weil die unlegirten und sehr harten Wolframkörner, welche an der Geschofsoberfläche zu Tage treten, die Züge beschädigen. Ueberdies findet während der Bearbeitung dieser Geschosse gröfserer oder geringerer Verlust an Wolfram statt, so dafs die Geschosse unter einander im Gewicht verschieden sind* Auch vermag man mit einer solchen gewöhnlichen Mischung das nothwendige specifische Gewicht gar nicht zu erreichen.Since the tungsten is alloyed with the other metals, it separates itself during rolling, Do not pull or press the alloy, as is the case with bullets, which only contain tungsten simple mix included. These latter bullets wear out the barrel quickly, because of the unalloyed and very hard tungsten grains on the surface of the bullet come to light, damage the trains. It also takes place during the processing of this Projectiles greater or lesser loss of tungsten instead, so that the projectiles under are different from one another in weight * One can also with such an ordinary one Mixture cannot at all achieve the necessary specific gravity.
Bei dem vorliegenden Geschofs sind diese Nachtheile ausgeschlossen, da man die Legirung sowohl im kalten als auch im warmen Zustande hämmern kann, ohne dafs sich Wolfram absondert. .Dies beweist der Umstand, dafs das Wolfram bei der Behandlung der Legirung mit Säuren sich als mehlfeines Pulver abscheidet. With the present storey these disadvantages are excluded, since the alloying can hammer both in the cold and in the warm state without tungsten secretes. This is shown by the fact that tungsten in the treatment of the alloy with acids separates out as a fine powder.
Der Wolframgehalt kann je nach den Forderungen, die man an das Geschofs stellt, vermindert oder erhöht werden. In allen Fällen mufs jedoch der Wolframgehalt ein hoher sein, weil ein Geschofs ein hohes specifisches Gewicht besitzen mufs.The tungsten content can be reduced depending on the demands placed on the storey or be increased. In all cases, however, the tungsten content must be higher because a bullet has a high specificity Must have weight.
Besteht das Geschofs aus ca. 20 pCt. Wolfram, die z. B. mit 80 pCt. Kupfer oder Nickel, vorzugsweise aber mit einer Kupfernickellegirung legirt werden, so kommt das specifische Gewicht desselben dem eines Hartbleigeschosses mit Stahlmantel gleich.If the storey consists of approx. 20 pCt. Tungsten, e.g. B. with 80 pCt. Copper or nickel, preferably but if they are alloyed with a copper-nickel alloy, then the specific gravity comes same as that of a hard lead bullet with a steel jacket.
Sobald man jedoch einen so hohen oder noch höheren Procentsatz von Wolfram anwendet, ist es empfehlenswerth, der Legirung beim Legirungsprocefs, also erst im Schmelzpunkt ca. 0,2 bis 1 pCt. Aluminium oder Magnesium hinzuzusetzen, weil dadurch die Legirung inniger und weniger spröde und hart wird, daher auch leichter zu bearbeiten ist.However, as soon as one uses such a high or even higher percentage of tungsten, it is advisable to start the alloying during the alloying process, i.e. only at the melting point approx. 0.2 to 1 pCt. To add aluminum or magnesium, because this makes the alloy more intimate and less brittle and hard is therefore easier to work with.
