【摘要】 论述了在显微偏析数值模拟研究中宏/微观模型的耦合数值方法和显微偏析模型与相图计算耦合的数值方法。宏/微观模型以潜热的处理为纽带,采用先进的迭代方法进行耦合;与相图的耦合是把与有关相图信息数据通过插值方法读入程序。这些方法为进行显微偏析数值模拟的研究提供了基础。更多还原

【Abstract】 Numerical method of maro/micro coupling and coupling of calculation of phase diagrams in simulation on microsegregation were discussed in this paper. Macro and micro models were coupled using iterative scheme through treatment of latent heat. Coupling with calculation of phase diagrams involves reading all information concerning the phase diagrams by linear interpolation method. These methods provide a base for numerical simulation on microsegregation.更多还原
