| Abstract Scope |
The details of dendrite growth in alloy solidification have been becoming clear due to the recent development of experimental and numerical techniques. Nevertheless, crucial problems are remaining in both experiment and simulation, such as low resolution in experiments and lack of material parameters in simulations. Thus, a new technology combining the cutting-edge techniques in experiment and simulation is required. Recently, the data-assimilation was applied to obtain the interfacial properties [Phys. Rev. E, 101 (2020) 052121]. Although it is the promising approach, the solidification microstructures obtained in experiment are often not perfect even using the state-of-the-art technology. In this study, we investigate the data-assimilation based on such limited observation data. Here, the phase-field method is employed as a material microstructure evaluation model. |
