Description

Aushärtbare Legierung Die Erfindung betrifft eine aushärtbare Legierung, dah. eine Legierung, bei der sich beim Schmelzvorgang die Legierungsbestandteile ineinander lösen und diese Lösung auch nach einem Abschrecken der Legierung aufrechterhalten bleibt, bei denen aber durch einen Anlassvorgang mit Temperaturen von etwa 400o ein Aushärten der Legierung eintritt. Bei diesem Anlassvorgang scheidet sich mindestens eine zweite Phase aus der Legierung aus, die die Härte der Legierung bedingt.. Bekannte Legierungen dieser Art sind beispielsweise Legierungen auf Kupferbasis, wie z.B. OuBe, CuCoBe, CuCr, CuNiSi. Erfindungsgemäß läßt sidh eine neue ausr ärtbare Legierung durch Verwaendunö einer Zinn- oder Phosphorbronze gewinnen, der Beryllium oder Kobalt oder Titan oder Chrom oder mehrere dieser Elemente gleichzeitig in solcher Menge zugesetzt ist, daß ihre Löslichkeit im Kupfer-Zinn-Mischkristall die bei den üblichen Anlaßtemperatizren um etwa 400o C gegebene übersteigt. Eine solche aushärtbare Legierung auf der Basis der Zinnbronzen hat gegenüber den bekannten neben der grossen Härte den Vorteil hoher chemischer Korrosionsfestigkeit, hoher Streckgrenze, hoher Ermüdungsfestigkeit und guter Schweissbarkeit. Man kann aus derartigen Legierungen uoao mit Vorteil DrIhte für endlose Metalltücher für Papiermaschinen herstellen. Eix Eine Legierung gemäss der Erfindung ist im abgeschreckten Zustand gut verarbeitbaro Man wird also vorteilhaft die VerarbeitunS der Leöierung bzwo hieraus hergestellter Drähte-etc. in abgeschrecktem Zustand vornehmen und das Aushärten nach der Verarbeitung, beispielsweise nach der Herstellung der genannten Metalltücher.Age-hardenable alloy The invention relates to an age-hardenable alloy, there an alloy in which the alloy components are separated during the melting process dissolve into one another and maintain this solution even after the alloy has been quenched remains, in which, however, by a starting process with temperatures of about 400o hardening of the alloy occurs. This starting process separates at least a second phase from the alloy, which determines the hardness of the alloy .. acquaintances Alloys of this type are, for example, copper-based alloys, e.g. OuBe, CuCoBe, CuCr, CuNiSi. According to the invention, a new hardenable alloy is available win by using a tin or phosphor bronze, beryllium or cobalt or titanium or chromium or several of these elements simultaneously in such an amount What is added is that their solubility in the copper-tin mixed crystal is that of the usual The tempering temperature exceeds the given temperature by about 400 ° C. Such an age-hardenable alloy on the base of the tin bronze has opposite the well-known in addition to the large hardness the advantage of high chemical corrosion resistance, high yield strength, high fatigue strength and good weldability. One can uoao with advantage from such alloys Manufacture wires for endless metal cloths for paper machines. Eix an alloy According to the invention, it is easy to process in the quenched state Advantageously, the processing of the oiling or wires etc. made from it. make in the quenched state and hardening after processing, for example after the production of said metal cloths.
