本文运用热力学理论对氮在灰铸铁溶液中的溶解度进行了理论研究,提出了铸造生产条件下灰铸铁溶液中氮的溶解度与温度和灰铸铁成分的关系式,并采用三种不同成分的灰铸铁材料对此做了验证。
The expressions of the dependence of the solubility of nitrogen in the moltengray cast iron on the temperature and composition of melts were advanced under the conditionsof foundry practice. Three gray cast iron specimens with different compositions were examinedin good agreement with derived expression.
