Microstructures generated by phase field simulated Al-Si solidification

Liquid phase fraction resulting from phase field simulations of the microstructure evolution during solidification of an AlSi7Mg0.3 alloy used for premeability simulations. RVE: cube of 150 micrometers edge length, resolution 0.5 micrometer. Format: VTK packed with gzip. Solidification conditions: 240 W/ccm heat extraction rate "equiaxed": No temperature gradient, xyz-periodic "directional": Temperature gradient 5K/mm, xy-periodic

本数据集为用于渗透率（permeability）模拟的AlSi7Mg0.3合金凝固过程中微观组织演化的相场模拟（phase field simulations）结果，包含液相体积分数相关数据。代表性体积单元（RVE, Representative Volume Element）为边长150微米的立方体，空间分辨率为0.5微米。文件格式为经gzip压缩的VTK格式文件。凝固条件统一采用240 W/ccm的热提取速率，具体工况分为两类：1. 等轴晶（equiaxed）工况：无温度梯度，xyz方向均为周期性边界条件；2. 定向凝固（directional）工况：温度梯度为5K/mm，xy方向均为周期性边界条件。
