The main emphasis of the present project is on the relevant microstructural phenomena which interact with each other in the TWIP/TRIP steel matrix. Our goal is to design a physically-based, computational multiphysics model that is able to match experimental observations of the structure-property relation. To reach this goal, we use a continuum dislocation dynamics model that is coupled to phase field approaches for fully resolved prediction of the formation of mechanical twins, as well as for the martensitic phase transformation.

本项目的主要重点是TTRIP/TRIP钢基体中相互作用的相关微观结构现象。我们的目标是设计一个基于物理的计算多物理场模型，该模型能够匹配结构-性质关系的实验观察。为了达到这一目标，我们使用一个连续位错动力学模型，耦合到相场的方法完全解决预测的机械孪晶的形成，以及马氏体相变。
