扩散和位移同时发生相变的热力学模型

A thermodynamical model for concurrent diffusive and displacive phase transitions

Mirko Maraldi, Luisa Molari, Diego Grandi

摘要:

提出了一个能够模拟扩散和位移相变的热力学一致的框架。该模型的控制方程为热力学热力学第一定律、线性动量平衡方程和溶质质量守恒的Cahn-Hilliard方程,并辅以适当选择的Helmholtz自由能和一致的边界条件和初始条件。

英文摘要:

A thermodynamically consistent framework able to model either diffusive and displacive phase transitions is proposed. The first law of thermodynamics, the balance of linear momentum equation and the Cahn-Hilliard equation for solute mass conservation are the governing equations of the model, which is complemented by a suitable choice of the Helmholtz free energy and consistent boundary and initial conditions.
