基于Ginzburg-Landau理论的相场法研究进展

Research Progress of Phase-field Method Based on Ginzburg-Landau Theory

介绍了相场法的原理,以及它的两个基本类型即连续相场法和微观相场法。对相场法在凝固过程、晶粒生长、固态相变、位错演化等方面的研究进展进行了综述。通过与其他模拟方法相比,指出了相场法的优点,并提出了相场模型在微观组织模拟、数值计算方法等方面存在的主要问题以及今后的发展方向。

The principle of phase-field method as well as its two basic types, i.e. continuous phase-field method and microscopic phase-field method, were introduced. The present development of phase-field method in solidification process, grain growth, solid-state phase transformation, dislocation evolution and so on were reviewed. The advantage of phase-field method was pointed out compared with other simulation methods. The main problems and the future research directions in microstructure simulation and numerical computational method were proposed.
