Description

Vergütung von Kupfer-Beryllium-Legierungen Die Erfindung betrifft die Vergütung von Kupfer-Nickel-Beryllium-Legierungen. Der Hauptzweck der Erfindung ist, ein Material darzustellen, welches solche Eigenschaften besitzt, daß man es für alle Zwecke, zu denen Jetzt Kupfer verwendet wird, benutzen kann, und welches außerdem noch durch entsprechende Wärmebehandlung Härte und Festigkeit erhält, die wesentlich größer sind als bei metallischem Kupfer.Quenching and tempering of copper-beryllium alloys The invention relates to the tempering of copper-nickel-beryllium alloys. The main purpose of the invention is to represent a material which possesses such properties that it can be for all purposes that now copper is used for, and what also receives hardness and strength through appropriate heat treatment, which are much larger than with metallic copper.

Es ist nun gefunden worden, daß diese Legierungen die Eigenschaft der Selbsthärtung besitzen, wenn sie in der Luft oder im Ofen von etwa goo° langsam abgekühlt werden. Die Abkühlung kann auch in der Weise erfolgen, daß die Temperatur von goo° C auf etwa 700° C während etwa i'/, Stunden zurückgeht und darauf die Abkühlung an der Luft erfolgt. Besonders günstig erweisen sich solche Legierungen, bei denen das Verhältnis von Nickel zu Beryllium etwa 13 : i beträgt. Eine Legierung mit 95,71 Kupfer, 4°'o Nikkel und 0,3'/" Beryllium erlangt nach der Vergiitung eine Härte von 86° Brinell, eine Zugfestigkeit von 50,7 kg pro Ouadratmillimeter -und eine Dehnung von 25 % bei 5 cm Meßlänge.It has now been found that these alloys have the property of self-hardening when they are slowly cooled in the air or in a furnace from about goo °. The cooling can also take place in such a way that the temperature falls from goo ° C. to about 700 ° C. for about 1.5 hours and then the cooling takes place in the air. Those alloys in which the ratio of nickel to beryllium is about 13: i have proven to be particularly favorable. An alloy with 95.71 copper, 4 ° nickel and 0.3 ° beryllium attains a hardness of 86 ° Brinell, a tensile strength of 50.7 kg per square millimeter - and an elongation of 25 % at 5 cm measuring length.

Auch der elektrische Widerstand der Legierungen wird durch diese Wärmebehandlung erniedrigt.This heat treatment also increases the electrical resistance of the alloys humiliated.
