Description

Verwendung von Nickel-Chrom-Eisenlegierungen für Gegenstände höchster Warmfestigkeit Zusatz zum Patent 73o 63o Die Erfindung bezieht sich auf die Verwendung von Legierungen zur Herstellung von solchen Gegenständen, die bei hohen Temperaturen, d. h. 5oo bis 9oo° C und gegebenenfalls darüber, höchste Warmfestigkeit aufweisen müssen. Gemäß Patent 73o 63o werden für diesen Zweck Legierungen verwendet, die 3o bis 70%, insbesondere 5o bis 70% Nickel, Io bis 25%'o Chrom, 57 bis I%, insbesondere 2o bis 50%o Eisen, 3 bis 12% Molybdän bziv. Wolfram, o bis q4oo Mangan, o bis 2%o Silicium, o,3 bis 2o% von einem oder mehreren der Elemente Tantal, Niob, Thorium, Titan enthalten.Use of nickel-chromium-iron alloys for items of the highest order Heat resistance Addition to patent 73o 63o The invention relates to the use of alloys for the production of such objects that, at high temperatures, d. H. 500 to 900 ° C and possibly above, have the highest heat resistance have to. According to patent 73o 63o, alloys are used for this purpose which 30 to 70%, in particular 50 to 70% nickel, 10 to 25% chromium, 57 to 1%, in particular 2o to 50% o iron, 3 to 12% molybdenum or Tungsten, o to 40000 manganese, o to 2% o Silicon, o, 3 to 2o% of one or more of the elements tantalum, niobium, thorium, Titanium included.

Es wurde nun gefunden, daß eine Steigerung der Warmfestigkeit von Legierungen, die die oben angegebenen Mengen an Nickel, Chrom, Eisen und Molybdän enthalten, auch dann eintritt, wenn man die Elemente Tantal, Niob, Thorium und Titan ganz oder teilweise durch Zirkon ersetzt, wobei der Zirkongehalt zweckmäßig o, I bis 6%'o betragen kann. Weiterhin wurde gefunden, daß man bei Zusatz von einem oder mehreren der Elemente Tantal, Niob, Thorium, Titan oder Zirkon zu hoch warmfesten Legierungen auf der Basis Nickel, Chrom, Eisen und Molybdän auch dann kommt, wenn man den Molybdängehalt bis zu o,5%o senkt, und schließlich auch dann, wenn der Nickelgehalt weniger als 3o%, aber nicht weniger als 2o% beträgt. Die Legierungen sind dabei im allgemeinen praktisch frei an Kohlenstoff, d. h. sie enthalten zweckmäßig nicht mehr als o,o4% Kohlenstoff.It has now been found that an increase in the heat resistance of Alloys containing the above amounts of nickel, chromium, iron and molybdenum contained, also occurs when one uses the elements tantalum, niobium, thorium and titanium completely or partially replaced by zirconium, the zirconium content expediently o, I up to 6% 'o. It has also been found that the addition of one or several of the elements tantalum, niobium, thorium, titanium or zirconium to be highly heat-resistant Alloys based on nickel, chromium, iron and molybdenum also come up when one lowers the molybdenum content up to o, 5% o, and finally also when the nickel content is less than 3o% but not less than 2o%. The alloys are included generally practically free of carbon, i. H. appropriately they do not contain more than 0.04% carbon.
