[SSL] Prof. Sung-Joon Kim: Fe-Zn reaction and its influence on microcracks during hot tensile Fe-Zn reaction was investigated by annealing a galvanized 22MnB5 steel sheet at 500–900 ° C for 5 min. The observed Fe-Zn intermetallic compounds within the coating depended on the annealing temperature.…
[ADL] Prof. Yoon-Uk Heo: Determination of Yield Stress in a Duplex Steel with a + c Lamellar Structure Yield stress ry is evaluated in a duplex steel with a + c lamellar structure by calculating the stress for the propagation of pile-up dislocations in one phase into another phase. Effective grain size of a lam…
[ATL] Prof. Yang Mo Koo: Effect of Al content on Magnetic Domains of {100} Grains in Electrical Steels Magnetic domains of {100} grains in electrical steels with 1.85 ≤ Al ≤ 6.54 wt. % were observed by magneto-optic Kerr microscopy. The characteristics and motion of magnetic domains were correlated with h…

[CTL] Prof. Jung-Wook Cho: oxide metallurgy during AM In laser metal deposition (LMD) process, meltpool oxidation is inevitable due to high working temperature, which results in finely dispersed non-metallic inclusions in the steel matrix. In this paper, cha…
[CTL] Prof. Jung-Wook Cho: Thermal history driven molecular structure transitions in alumino-borosilicate glass The glass network structure governs various thermos-physical properties such as viscosity, thermal, and electrical conductivities, and crystallization kinetics. We investigated the effect of temperature o…
[CSL] Prof. Youn-Bae Kang: ISIJ International, Vol. 58(2018), No. 7, pp.1257-1266 In order to elucidate possible mechanism causing nozzle clogging during continuous casting of Ti added Ultra Low C (Ti-ULC) steel, thermodynamic analysis and experimental validation were carried out with …
[ATL] Prof. Se Kyun Kwon: Twinning in metastable high-entropy alloys Twinning is a fundamental mechanism behind the simultaneous increase of strength and ductility in medium- and high-entropy alloys, but its operation is not yet well understood, which limits their exploita…
[EML] Prof. Sung-Mo Jung: ISIJ International, Vol. 58 (2018), No. 2, pp.2744-281 In a 2 stage-smelting reduction process, it is favorable to lower the reduction degree of iron ore in a pre-reducing unit by lowering its temperature to avoid any troubles due to stickiness of high reduce…
Prof. Han Soo Kim developed ultrastrong, ductile, low-density steels For nearly six thousand years since the dawn of Bronze Age when early civilizations started alloying copper with tin, zinc or arsenic, alchemists and scientists have long explored the properties of metallic …
Prof. Se Kyun Kwon develops a New Theory for Plasticity of Face-Centered Cubic Metals The fundamental concepts of physics are crucial to understand the correlation of the structure and strength of materials. Some materials, like a steel coil spring or rubber, are elastic. Grasping a rubber bal…
