Creation of Materials by Super-Thermal Field 2025 (CMSTF2025) 

 We are pleased to announce that the 2nd international symposium on Creation of Materials by Superthermal Field 2025 (CMSTF2025) will be held in Osaka, Japan from December 8 to 13, 2025, as a symposium of Materials Research Meeting (MRM 2025), which is the first cross-disciplinary international conference in Japan launched by the Materials Research Society of Japan (MRS-J) in 2019.

This conference is held as a part of the project "Creation of Materials by Super-Thermal Field: Neo-3D printing by Manipulating Atomic Arrangement through Giant Potential Gradient". The target of this area is the mechanisms of unique crystal growth under super-thermal fields generated by local heating by electron beams or lasers, which have been found to occur in metal 3D printing (3DP). Studies conducted in this project include, "Advanced in-situ observations, such as high-speed temperature field analysis", "Synchrotron X-ray transmission imaging", Computer Simulations, such as computational thermal fluid dynamics (CtFD), phase-field (PF) method, molecular dynamics (MD), and their validation by experiments to elucidate the mechanisms. Furthermore, artificial intelligence to analyze the process of microstructure to structure performance correlation and establish the Science for Creation of Materials by Super-Thermal Field, which contributes to the creation of new materials, such as 3DP of single-crystals. The outcomes will contribute to a great novelty in materials science.

The scope of this symposium includes, but not limited to, scientific studies on experiments, computer simulations, and data sciences related to the following topics

· Interactions between quantum beams and materials in the formation of super-thermal fields

· Crystal growth in super-thermal fields represented by the temperature gradient higher than 10 M K/m

· Large thermal strain and their relaxation

· Giant Marangoni effect associated with these phenomena

· Creation of new materials by utilizing the super-thermal field

· Microstructure and material properties of materials grown in the super-thermal field

We look forward to welcoming you to Yokohama to participate in the conference with your valuable contributions and insights.
