Finite Element Analysis on ZAlCu4 Alloy Phase Change Heat Transfer in Solidification

根据相变热传导的等效热容法有限元理论 ,对ZAlCu4合金凝固过程的温度场进行了瞬态求解 ,分析铸件长度方向上各点处的温度值随时间的变化关系 ,以及在不同时刻长度方向上各点的温度分布。计算结果与实测值吻合得较好 ,这为模拟ZAlCu4合金在凝固过程中微观组织的演化过程奠定了理论基础和前提条件。

The transient temperature field distribution of ZAlCu4 alloy phase change heat transfer process was analyzed based on equivalent thermal entropy method in solidification. Some results were obtained, such as the relationship between temperature and time of different points in the direction of coordinate axis Z, the relationship between temperature and points’ locations on different times, which agreed very well with experiments ones, this will do much contribution to the theoretic base and prerequisite for the simulation of microstructure evolution process ZAlCu4 alloy in solidification.
