Description

  

      Zusatzpatent    zum Hauptpatent Nr. 227628.    Feder aus     Nickel-Eisenlegierung,    insbesondere für     thermokompensierte        Schwingsysteme.       Im Hauptpatent Nr. 227628 ist     eine    Feder  aus     Nickel-Eisenlegierung    mit härtendem     Be-          rylliumzusatz,    insbesondere für     thermokom-          pensierte    Schwingsysteme beschrieben, die da  durch gekennzeichnet ist, dass die Legierung  aus 25 bis 40% Nickel, 0,5 bis 2     %    Beryllium,  0,5 bis 2 % Titan, 5 bis 12 ,

  wo mindestens eines       Metalles    der Chromgruppe, 0,2 bis<B>0,8%</B> Koh  lenstoff und dem Rest im wesentlichen aus  Eisen besteht, wobei diese Mengenverhältnisse  so zueinander abgestimmt sind, dass ausser der  erzielten hohen Härte und dem kleinen Tem  peraturkoeffizienten des     Elastizitätsmoduls     der Feder die     Temperatur-Gangkurve    eines  mit dieser Feder betriebenen     Schwingsystems     im Temperaturbereich von 0 bis     -f-    40' prak  tisch geradlinig verläuft.  



  Fabrikationsversuche mit grösseren Nor  malschmelzen haben nun ergeben, dass der       Curie-Punkt    durch den     Kohlenstoffzusatz    wie  erwartet nach oben verschoben wurde, aber  weiter als ursprünglich an kleinen Versuchs  schmelzen ermittelt werden konnte. Für eine       Reihe    von Anwendungen ist es     erwünscht,     dass der     Curie-Punkt    zwischen     +    400 und       -i-   <B>801</B> C liegt. Bei Schmelzen mit über 0,2    Kohlenstoff liegt der     Curie-Punkt,    wie an  den grossen Normalschmelzen festgestellt  wurde, zwischen     -f-    80" und     +    100  C..

   Um  den     Curie-Punkt    in den für gewisse Fälle er  wünschten Bereich von     -j--    400 bis     +        8011    C zu  verlegen, muss der Kohlenstoffgehalt unter  0,2 % gehalten werden.



      Additional patent to main patent no. 227628. Spring made of nickel-iron alloy, especially for thermo-compensated oscillating systems. The main patent no. 227628 describes a spring made of nickel-iron alloy with hardening beryllium additive, especially for thermocompensated oscillating systems, which is characterized in that the alloy consists of 25 to 40% nickel, 0.5 to 2% beryllium, 0.5 to 2% titanium, 5 to 12,

  where at least one metal of the chromium group, 0.2 to 0.8% carbon and the remainder consists essentially of iron, these proportions being matched to one another so that in addition to the high hardness achieved and the small Tem perature coefficient of the elastic modulus of the spring, the temperature-course curve of an oscillating system operated with this spring in the temperature range from 0 to -f- 40 'runs practically in a straight line.



  Manufacturing tests with larger standard melts have now shown that the Curie point was shifted upwards as a result of the addition of carbon, but could be determined further than originally on small test melts. For a number of applications it is desirable that the Curie point be between + 400 and -i- 801 C. For melts with more than 0.2 carbon, the Curie point, as has been determined in the large normal melts, is between -f- 80 "and + 100 C ..

   In order to move the Curie point in the range from -j-- 400 to + 8011 C, which is desired for certain cases, the carbon content must be kept below 0.2%.
