论文摘要
我们提出了一种相晶晶体（PFC）模型，用于固化，该模型解释了热传输和温度依赖性晶格参数。弹性效应是通过从微观密度场计算出的连续弹性场来表征的。我们通过选定的数值研究展示了模型功能，该数字研究的重点是熔体的二维晶体的典型生长，从而产生了面形状和树突。这项工作为综合的固化模型设定了理由，包括热膨胀。
We present a phase-field crystal (PFC) model for solidification that accounts for thermal transport and a temperature-dependent lattice parameter. Elasticity effects are characterized through the continuous elastic field computed from the microscopic density field. We showcase the model capabilities via selected numerical investigations which focus on the prototypical growth of two-dimensional crystals from the melt, resulting in faceted shapes and dendrites. This work sets the grounds for a comprehensive mesoscale model of solidification including thermal expansion.
