Description

Vergütung von Kupfer-Beryllium-Legierungen Es ist vorgeschlagen worden, Kupfer-Beryllium-Legierungen mit einem 'Nickelgehalt bis etwa io "/" von höheren Temperaturen vorzugsweise oberhalb 6oo° C hinreichend schnell abzukühlen oder abzuschrecken und gegebenenfalls anschließend durch Erhitzen auf niedrigere Temperaturen künstlich zu altern und dadurch zu vergüten.Quenching and tempering of copper-beryllium alloys It has been proposed that Copper-beryllium alloys with a nickel content of up to about 10 "/" higher Cool down or quench temperatures preferably above 600 ° C sufficiently quickly and if necessary then artificially by heating to lower temperatures to age and thus to be remunerated.

Demgegenüber ist gefunden worden. daß ein ähnliches Vergütungsverfahren, bestehend im Abschrecken von Temperaturen oberhalb 9oo° und in künstlichem Altern bei Temperaturen zwischen 350 und 700°, auch bei Legierungen mit Nickelgehalten von i i bis ,4o "(" und Berylliumgehalten von o, i bis 201, anwendbar ist. Besonders günstige Vergiftungsergebnisse werden erzielt, wenn der Nickelgehalt sich zum Berylliumgehalt in der Legierung wie 13 : 1 verhält. Legierungen dieser Art besitzen nach der angegebenen Wärmebehandlung eine Brinellhärte von i io, eine Zugfestigkeit von 63 kg pro qmm und eine Dehnung von 15 °/" bei 5 cm Meßlänge. Sie zeigen keine wesentliche Verminderung der Härte unter der Einwirkung der Hitze bis zu einer Temperatur von 700° C. Diese Legierungen stellen ein Material dar, welches solche Eigenschaften besitzt, daß man es für alle Zwecke, zu denen jetzt Kupfer verwendet wird, benutzen kann und «-elches außerdem durch die Wärmebehandlung Härte und Festigkeit erhält, die wesentlich größer sind als bei metallischem Kupfer. Die Legierungen besitzen im vergüteten Zustand auch gute elektrische Leitfähigkeit.In contrast, it has been found. that a similar tempering process, consisting of quenching at temperatures above 900 ° and artificial aging at temperatures between 350 and 700 °, can also be used for alloys with nickel contents of 2 to 40 "(" and beryllium contents of 0.1 to 201. Particularly favorable poisoning results are achieved if the nickel content is related to the beryllium content in the alloy as 13: 1. Alloys of this type have a Brinell hardness of i io, a tensile strength of 63 kg per square mm and an elongation of 15 ° / "after the specified heat treatment. They show no significant reduction in hardness under the action of heat up to a temperature of 700 ° C. These alloys are a material which has such properties that it is used for all purposes for which copper is now used is, can use and «-elches also receives hardness and strength through the heat treatment, which are much greater than with metallic em copper. In the quenched and tempered condition, the alloys also have good electrical conductivity.
