Blei-Natriumlegierung. Patentiert im Deutschen Reiche vom 25. März 1917 ab. Lead-sodium alloy. Patented in the German Empire on March 25, 1917.
Es ist schon festgestellt worden, daß die Sprödigkeit von Blei-Natriumlegierung durch Zusatz von Zinn vermindert werden kann. Auch auf die günstige Wirkung eines weiteren Zusatzes von Kupfer ist bereits hingewiesen worden. Weitere Versuche haben nun gezeigt, daß der Kupferzusatz zu Blei-Natriumlegierungen auch allein eine günstige Einwirkung hat insofern, als die Legierung zäher wird ίο und nicht reißt, falls sie Wärmespannungen ausgesetzt ist. Der Zusatz von Kupfer zu Blei-Natriumlegierungen bewirkt eine außerordentliche Verfeinerung des Bruchkornes. Hierbei muß jedoch die Kupfermenge geringer als 1Z2 Prozent sein. Eine geeignete Legierung J5 entsteht z. B. bei einem Na-Gehalt von ι Prozent und einem Cu-Gehalt von 0,2 Prozent.It has already been found that the brittleness of lead-sodium alloy can be reduced by adding tin. The beneficial effect of a further addition of copper has already been pointed out. Further tests have now shown that the addition of copper to lead-sodium alloys alone has a beneficial effect insofar as the alloy becomes tougher and does not tear if it is exposed to thermal stresses. The addition of copper to lead-sodium alloys causes an extraordinary refinement of the broken grain. Here, however, the amount of copper must be less than 1 Z 2 percent. A suitable alloy J 5 is produced, for. B. with an Na content of ι percent and a Cu content of 0.2 percent.
