Shohei, Uranaka (Assistant Professor) received Sawamura Award at The Iron and Steel Institute of Japan (ISIJ)

Date of Award：2025-03-08

Name, Faculty/Graduate School, Department (Stream / Program) / Major: ：Department of Systems Innovation, Kawabata Lab

Name of the award and a short explanation about the award：”Sawamura Award” An award presented to authors of papers published in the English-language academic journal “ISIJ International” during the previous year that are deemed to be the most academically and technically beneficial.

About awarded research：”Quantitative Analysis of Hardening Due to Carbon in Solid Solution in Martensitic Steels” In carbon steels, controlling the hardness of the martensite microstructure is important for achieving high strength and high performance. However, while it is understood that the hardness of martensite is influenced by solid solution carbon, dislocations, grain size, and precipitates, the extent of each influence has not been clearly explained. In this paper, we quantitatively evaluate the influence of solid solution C on martensite hardness and attempt to elucidate the origin of martensite hardness. By quantitatively determining solid solution C through electrical resistivity measurements and precisely quantifying dislocation density and microstructure, we quantitatively evaluated the effects of solid solution C, dislocations, precipitates, grain boundaries, and restained austenite on strength and hardness, clearly demonstrating that solid solution C significantly contributes to strength development.

Awardee’s impression & future plan：I am truly honored to receive this prestigious award. I would like to express my sincere gratitude to my co-authors for their invaluable guidance and support in the writing of this paper. I will continue to devote myself to contributing to the advancement of steel materials.

Langxing, TAN (D4) received Outstanding Student Award at the 49th Symposium on Composite Materials

Date of Award：2024.9.20 Name, Faculty/Graduate School, Department (Stream / Program) / Major：TAN Langxing (School of Engineering, Department of Systems Innovation, and D4) Name of the award and a short explanation about the award：Outstanding Student Award (This award is given to students whose research on composite materials has been presented at the conference with outstanding novelty and logic. This year, one student received the Hayashi Student Award (Grand Prize) and three students received the Outstanding Student Award.) About awarded research：Theoretical investigation on scattering of ultrasonic Lamb waves at impact damage in quasi-isotropic CFRP laminates Awardee’s impression & future plan：I have received the Outstanding Student Award at the 49th Symposium on Composite Materials held by Japan Society for Composite Materials. In this research, we have established a theoretical analysis method for scattered waves in damaged areas of CFRP laminates, which is expected to contribute to the construction of an impact damage detection method based on scattered waves. I would like to express my sincere appreciation to Professor Yoji Okabe, Assistant Professor Osamu Saito, and all the members of our laboratory for their continuous support and guidance.
