本文测定了微量元素Na对Al-Si共晶温度的影响,并应用热力学基本原理计算了Al-Si体系加Na后共晶析出温度的变化。结果表明,测得的数据与计算的结果是一致的。
In this paper, the influence of trace element Na on the eutectic temperature of Al-Si was investigated. The change of eutectic temperature of Al-Si system after adding Na was calculated by the basic principles of thermodynamics. The results show that the measured data is consistent with the calculated results.
