Description

Verfahren zur Herstellung von Gegenständen hoher Steifigkeit und Federkraft Zusatz zum Patent 611 a56 Im Patent 6r t 256 ist ein Verfahren beschrieben, nach welchem Gegenstände hoher Steifigkeit und Federkraft aus Legierungen mit 55 bis 85% Nickel, zo bis q.0% Chrom, o bis 2o % Eisen und über 5 bis 15% Molybdän, wobei das Molybdän ganz oder teilweise durch Wolfram .ersetzt sein kann, dadurch ,erzieIt werden, daß man die Gegenstände auf q.oo bis 700° .erhitzt. Die Erhitzungsdauer kann dabei bis zu mehreren Stunden betragen. Es wurde festgestellt, daß das gleiche Verfahren auch bei Gegenständen aus Legierungen zum Ziel führt, die lediglich aus Nickel, Chrom und gegebenenfalls Eisen in den vorstehend angegebenen Mengenverhältnissen bestehen. Die Legierungen können außerdem geringe Mengen an Molybdän, d. h. unterhalb 5 %, enthalten. Das Molybdän kann auch ganz oder teilweise durch Wolfram ersetzt sein. Außerdem können noch geringe Mengen an Desoxydations- oder Verarbeitungszusätzen, wie beispielsweise Silicium Moder Mangan, vorhanden .sein. Auch hier zeigt sich, daß sowohl die Süeifigkeit wie die Federkraft durch Vorbehandlung bei q:oo bis 700°, insbesondere etwa bei 6oo°, ganz erheblich gesteigert werden.Process for the production of objects of high stiffness and spring force Addition to patent 61 1 a56 In patent 6r t 256 a process is described by which objects of high stiffness and spring force from alloys with 55 to 85% nickel, zo to q 0% chromium, or the like is described Up to 20% iron and more than 5 to 15% molybdenum, the molybdenum being completely or partially replaced by tungsten, can be achieved by heating the objects to between 100 and 700 °. The heating time can be up to several hours. It has been found that the same method also works with objects made of alloys which consist only of nickel, chromium and optionally iron in the proportions given above. The alloys can also contain small amounts of molybdenum, ie below 5%. The molybdenum can also be completely or partially replaced by tungsten. In addition, small amounts of deoxidizing additives or processing additives, such as silicon moderate manganese, may be present. Here, too, it can be seen that both the smoothness and the spring force can be increased quite considerably by pretreatment at q: oo to 700 °, in particular around 600 °.
