| 摘 要： | 基于当量的概念（所有合金元素对材料热物理性能的影响可以通过一个参考元素的等效作用来表示），以Zn为参考元素，通过对7XXX系铝合金二元相图富Al端液相线的数值拟合，得到当量算法所需参数，并将其他元素的当量浓度和参考元素的实际浓度之和用于计算材料的液相线温度和潜热。计算结果与差示扫描量热仪（DSC）测得的数据吻合。与Jmatpro软件获得的数值相比，该算法展现出更好的准确性。

| Abstract: | Based on the equivalency method (the impact of all alloying elements on the thermo-physical properties can be expressed through the equivalent impact of a reference element), Zn was regarded as a reference element, and the parameters required for equivalency calculation were obtained through the numerical fitting of the Al-rich liquidus line in the binary phase diagram of 7XXX series aluminum alloys. The sum of the equivalent concentration of other elements and the actual concentration of the reference element was used to calculate the liquidus temperature and latent heat of materials. The calculation results are in good agreement with the measured data by differential scanning calorimetric (DSC) apparatus. Compared with Jmatpro software, the equivalency method shows better accuracy. |
