摘　　要：对半固态ZL104合金的填充与凝固过程进行了数学模拟与实验验证。结果表明,在不同的充型速度下,各个浇道中温度场的差别不大;缩松气孔缺陷的总体积会伴随着充型速度的增加而变大,但并不是充型速度越小越好,ZL104合金的适宜充型速度为3 m/s;ZL104合金铸件的实际凝固组织与数学模拟得到的模拟结果是一致的。Mathematical simulation and experimental verification of the filling and solidification process for semi-solid ZL104 alloy were conducted. The results show that the difference of the temperature field at each runner is small under the different filling velocity. The volume of the defects increase accompanied with the increase of filling velocity, but it is not filling velocity as small as possible, the suitable filling velocity of ZL104 alloy is 3 m/s. The results of mathematical simulation has good consistent with the actual solidification structure of ZL104 alloy.
