摘　　要：以Al-Cu-Mg三元共晶合金为研究对象,采用石墨保温型凝固的方法,对三元共晶合金进行了凝固路径的研究,并采用数学模型对凝固过程进行了模拟。结果表明,Al-Cu-Mg三元共晶反应的凝固路径为:(L+α或L+T)→(L+α+T)→(L+α+T+β);模拟计算结果与实验结果具有较好的一致性。Taking Al-Cu-Mg ternary eutectic alloy as research object, the solidification paths of ternary eutectic alloy were studied through the method of graphite insulation type solidification, and the solidification process was simulated by mathematical model. The results show that the solidification path of Al-Cu-Mg ternary eutectic reaction is （L＋α or L＋T）→ （L＋α＋T）→（L＋α＋T＋β）, the simulation results are good agreement with experimental results.
