Die Erfindung betrifft Silberlegierungen, die sich zur Herstellung von Regelstäben für Neutronenreaktoren eignen und überlegene Festigkeitseigenschaften aufweisen.The invention relates to silver alloys that are Suitable for the production of control rods for neutron reactors and superior strength properties exhibit.
Die erfindungsgemäßen Legierungen stellen im wesentlichen eine Weiterentwicklung einer Legierung dar, die Gegenstand des nicht zum Stand der Technik gehörenden Patents 1 062 839 ist. Diese Legierung weist nukleare Eigenschaften auf, die sie als Werkstoff für die Regelstäbe von Neutronenreaktoren recht geeignet erscheinen läßt. Sie besteht aus 2 bis 20 Gewichtsprozent Indium, gegebenenfalls bis 10% Cadmium und Rest nicht über 85 Gewichtsprozent Silber. Diese Legierung besitzt zwar einen erwiesenen nuklearen Wert, weist aber nur eine solche Festigkeit auf, daß ihr Einsatz bei bestimmten Verwendungszwecken beschränkt ist.The alloys according to the invention essentially represent a further development of an alloy which is the subject of non-prior art patent 1,062,839. This alloy has nuclear properties that make it right as a material for the control rods of neutron reactors seems suitable. It consists of 2 to 20 percent by weight indium, possibly up to 10% cadmium and the balance not exceeding 85 weight percent silver. This alloy has a proven one nuclear value, but has only such strength that its use in certain uses is limited.
Es wurde nun gefunden, daß dieser Nachteil der Silber-Indium- bzw. Silber-Indium-Cadmium-Legierung durch Zusatz eines Edelmetalls der Gruppe Platin, Ruthenium, Rhodium, Osmium und Palladium in Mengen von 0,5 bis 1,5 Gewichtsprozent zur Grundlegierung beseitigt werden kann. Die Auswirkung dieses Metallzusatzes ist deutlicher aus der folgenden Tabelle zu ersehen.It has now been found that this disadvantage of the silver-indium or silver-indium-cadmium alloy by adding a noble metal from the group of platinum, ruthenium, rhodium, osmium and palladium can be removed from the base alloy in amounts of 0.5 to 1.5 percent by weight. The effect this metal addition can be seen more clearly in the following table.

Die Herstellung der erfindungsgemäßenLegierungen kann nach irgendeiner der üblichen Methoden erfolgen. Die Legierung kann leicht hergestellt werden, indem man die gewünschten Bestandteile in einen Graphittiegel eingibt. Die Bestandteile können dann mittels einer Induktionsheizeinrichtung oder auf irgendeinem anderen geeigneten Wege geschmolzen werden. Zur Verhinderung einer Oxydation der geschmolzenen Legierung wird auf die Oberfläche der Schmelze eine Schutzdeckschicht aus kalzinierten Kokspellets aufgebracht. Die Legierung kann nach dem Schmelzen nach irgendeiner der üblichen Methoden gegossen werden.The alloys of the present invention can be prepared by any of the conventional methods. The alloy can be easily made by putting the desired ingredients into one Entering graphite crucible. The components can then by means of an induction heating device or on any other suitable means. To prevent oxidation of the melted A protective coating of calcined alloy is applied to the surface of the melt Coke pellets applied. The alloy can after melting by any of the usual Methods to be poured.
