研究了氮对双联电渣法生产的Cr20Ni80电热合金锻造塑性的影响，指出合金含氟量超过0．030％时使造塑性开始下降，超过0.035％时显著恶化，并对造成锻造塑性下降的原因进行了分析讨论。
The effect of nitrogen on the forging ductility of Cr20Ni80 electric alloy produced by the double electroslag method was studied. The results show that the ductility begins to decrease when the content of fluorine in the alloy exceeds 0.030%, and significantly deteriorates when the content exceeds 0.035% Analyzed and discussed.
