中文摘要：介绍了微观相场的动力学模型以及运用相场法对镍基合金沉淀过程界面演化规律取得的研究进展。该模型可成功描述合金沉淀过程中沉淀相形貌和结构的演化，得到一系列的场变量、沉淀相界面结构、界面迁移性等性质。利用该模型已经对许多先进镍基合金的相变动力学进行了模拟研究。
英文摘要：The microscopic phase-field dynamics model as well as the development of interface evolution law of nickel-based alloy during precipitation process by phase-field method were introduced. The model can be successfully used to describe precipitation phase morphology and structure evolution of the alloy during precipitation process, and get a set of field variables, precipitation phase interface structure, interface transference character and so on. Using this model, the simulation investigations have been made on the phase transition kinetics of many advanced nickel-based alloys.
