Park Yoon-ji (Class of ’25, Master’s program), a student in the Department of New Materials Engineering at Kookmin University, received the “Yeh Award for Outstanding Paper” presented by the High-Entropy Alloys Subcommittee of the Korean Society of Metals and Materials in 2026.
​
At the “2026 Fall Conference of the Korean Society of Metals and Materials,” held at the Daejeon Convention Center (DCC) from October 28 to 30, Park Yun-ji received the Outstanding Paper Award for her research on the fatigue crack propagation behavior of high-entropy alloys, conducted under the guidance of Professor Sung Hyokyung.
​
The award-winning paper, titled “Near-threshold fatigue crack propagation in a CoCrFeMnNi high-entropy alloy: The role of microstructural state and crack-boundary interaction,” was published as the first author in the *Journal of Materials Science & Technology*, an SCIE-indexed international journal ranked in the top 0.5% of the metallurgical engineering field according to the 2025 JCR.
​
This study analyzed how the growth patterns of cracks induced by cyclic loading vary depending on the microstructure of high-entropy alloys and, based on these findings, proposed strategies for enhancing the material’s fatigue resistance.
