Abstract Scope |
Phase field aided design plays a more and more important role in material design, material processing control and optimization. Integrating continuous phase field model, first principle calculation and dislocation dynamics calculation aided experimental design, a new type of spinodal decomposition strengthened ultra-high specific strength magnesium alloy and high strength/high toughness copper alloy were prepared. Based on the unity of the classical thermodynamic free energy model, integrate the multi-level phase field simulation of microstructure (continuous phase field, crystal phase field and micro diffusion phase field), the simulation of macro process multi field (flow field, temperature field and defect prediction) and the casting body data and process knowledge information, and design and optimize the liquid forming process of alloy structural parts and typical cases across scales are presented; Finally, the thinking and Prospect of integrated computing materials technology for engineering applications are introduced. |
