采用具有薄界面极限参数的三维相场模型研究了铝-4.5质量%铜合金的自由枝晶生长。在给定的界面能各向异性强度下,测量了枝晶生长速度和尖端曲率半径,并确定了不同过冷程度下的稳定性参数。将所得的枝晶生长速度与LKT (Lipton, Kurz和Trivedi)模型进行了比较,并定量讨论了稳定性参数的作用。
The free dendrite growth of aluminum-4.5 mass%copper alloy has been investigated using a three-dimensional phase-field model with thin-interface-limit parameters. The dendrite growth velocity and the tip radius of curvature are measured for a given value of anisotropy intensity of the interface energy, and the stability parameters are determined at different degrees of undercooling. The dendrite growth velocities are compared with those obtained by LKT (Lipton, Kurz and Trivedi) model, and the role of the stability parameter is quantitatively discussed.
