场变量模型在材料微观结构演化中的应用

Field Variables Model for Microstructure Evolution in Materials

摘要:

采用场变量模型来模拟材料微观结构的演变过程取得了非常大的进展，已成为描述材料微观结构演化的非常成功的模型之一。通过定义一系列高阶可微的保守场和非保守场变量来表述微观组织的空间分布，采用计算机模拟来描述这些场变量的变化路径，从而很好地预测及控制微观组织演化过程。本文详细介绍了场变量模型的基本原理及其在材料科学与工程各领域应用的最新进展。

Abstract:

The field variables model has recently emerged as a powerful approach for simulating microstructure evolution in materials. It describes the microstructure using a set of conserved and non-conserved field variables in the form of higher order differentials. It can predict and control complex microstructure evolution with these field variables by computer simulation. This paper reviews the fundamental principle of the field variables model and recent progress in the field of materials science and engineering.
