~Presentation by Assistant Professor Masayuki Okugawa～

Dr. Masayuki Okugawa was selected as a Keynote Speaker at the symposium “MODELING AND SIMULATION FOR ADDITIVE MANUFACTURING” at the World Congress on Computational Mechanics (WCCM2024). He was selected as a Keynote Speaker. Solute segregation in a rapidly solidified Hastelloy-X Ni-based superalloy during laser powder bed fusion investigated by phase-field simulations and computational thermal-fluid dynamics, Addit. The presentation focused on the contents of the paper.

　　　　　　

He introduced the results of research conducted in our laboratory on the formation of solidification structure and solute segregation formed by hyperthermal field, rapid temperature rise, and rapid cooling in laser PBF, and on the prediction and alloy design using thermohydrodynamic and phase-field calculations, and received many questions from the audience.

　　　　　　　　　　　　　　　　　

　　　　　　　　　　　　　　　　　　　　

～Presentation by Professor Yuichiro Koizumi~

Professor Koizumi presented the research results of Sousuke Kanegae, who completed his doctoral program and received his degree this spring.

The contents are as follows

The design and experimental verification of a lattice structure that exhibits stress-induced phase transition and shock-absorbing performance under multi-directional loading, and the development of a lattice structure that exhibits stress-induced phase transition followed by thermally induced phase transition due to temperature change, using a cladding material (bimetal) with different thermal expansion coefficients as a part of the lattice. The concept of PXCM and prediction of its properties by computational mechanics. The results of research on experimental evaluation (joint research with Mr. Jun Nagayama) were introduced.

This research is also a cornerstone for expanding the research on materials creation, which is currently being conducted in Creation of Materials by Super Thermal Field, to research on the creation of functional metamaterials.

　　　　　　　　　　　　　　　　　　　　　　

Prof. Koizumi also served as an organizer and session chair for the research mainly using the phase-field method.
