Performance of Gadolinium-Neutron Shielding Layer Formed by Plasma Thermal Spray Method
플라스마 용사법으로 제조된 Gd-중성자 차폐막의 성능
Youl Baik, Dong Geon Lee, Jong Jae Lee, Yong Choi백열, 이동건, 이종재, 최용
Korean J. Met. Mater.
2025;63(1):68-74. Published online 2025 Jan 5
DOI:
https://doi.org/10.3365/KJMM.2025.63.1.68
Abstract
Plasma thermal spray coating method was applied to prepare a high performance neutron shielding layer for various applications such as nuclear spent fuel transportation and storage containers and experimental research reactors. In this study, layers with various compositions of a gadolinium oxide neutron absorber and a nickel alloy binder on.....

Preparation of Electroformed Copper-Nickel Multi-Nano-Layers and Characterization of Their Electromagnetic Shielding Effectiveness
구리-니켈 다층 나노 도막 제조와 전자파 차폐 효과 평가
Yong Choi최용
Korean J. Met. Mater.
2020;58(9):639-644. Published online 2020 Aug 19
DOI:
https://doi.org/10.3365/KJMM.2020.58.9.639
Abstract
Thin copper-nickel foil with multi-nano layers was prepared by pulse-electroforming to develop a high performance electromagnetic shielding material for electronic devices. The pulse electroforming conditions of the aqueous solution chemistry were selected based on the aqueous copper-nickel-sulfur phase diagram and an evaluation of the deposition rate using the finite element.....

Study on the Effect of the Thiourea on Nano-Mechanical Properties and Microstructures of the Electroformed Thin Ni-P Foil
Moo Young Jung, Chang Su Nam, Byung-Sik Lee, Yong Choi
Korean J. Met. Mater.
2020;58(1):1-6. Published online 2020 Jan 1
DOI:
https://doi.org/10.3365/KJMM.2020.58.1.1
Abstract
The effect of thiourea on the nano-mechanical and chemical properties of Ni-P foil was studied to develop a high performance Ni-P deposit for automobile and machinery parts. The Ni-P deposit was prepared by electroforming in a modified sulphate bath with different amounts of thiourea. Chemical analysis of the electrodeposited Ni-P.....

Study on the Mechanical Properties and Corrosion Behaviors of Fe-(20, 45) wt% Gd Intermetallics
Fe-(20, 45) wt% Gd 금속간 화합물의 기계적 특성 및 부식 거동 연구
Bo Kyeong Kang, Youl Baik, Yong Choi, Byung Moon Moon강보경, 백열, 최용, 문병문
Korean J. Met. Mater.
2017;55(2):91-97. Published online 2017 Feb 2
DOI:
https://doi.org/10.3365/KJMM.2017.55.2.91
Abstract
Fe-(20, 45 wt%) Gd intermetallics were vacuum arc melted as the mother alloy of a neutron shielding and absorbing material. The structure of the cast Fe-20 wt% Gd intermetallics had primary dendrites with a short width of about 2 μm, which became coarse with increasing Gd content. The final compositions.....
