Enhancement of Flexural Strength by Slip Casting Cordierite Ceramics with h-BN Nanoparticles
Chul Oh Park, Jong Hyun Lee, Dong Kyun Lee, Hyun Jun Cho, Sung Hwan Yim, Kyu Hyoung Lee
Korean J. Met. Mater. 2024;62(4):306-311.   Published online 2024 Mar 29
DOI: https://doi.org/10.3365/KJMM.2024.62.4.306

Abstract
In this study, we enhanced the flexural strength of cordierite ceramics by incorporating h-BN (hexagonal boron nitride) nanoparticles, facilitated by the slip casting process. Initially, commercial cordierite powder with an average particle size of 10 mm underwent a ball-milling process to reduce the size to 2.5 mm and simultaneously achieve..... More

                
Effect of Ion Flux Variation in DC Magnetron Sputtering on the Deposition of Cubic Boron Nitride Film

Korean J. Met. Mater. 2023;61(11):824-829.   Published online 2023 Oct 29
DOI: https://doi.org/10.3365/KJMM.2023.61.11.824

Abstract
Cubic boron nitride (cBN) thin films were deposited using DC magnetron sputtering, and the effect of the ion flux on the deposition behavior and residual stress of the cBN thin films was investigated. To increase the ion flux, the magnetic force ratio of the central/peripheral permanent magnets inserted in the..... More

                
Synthesis of Three-Dimensionally Interconnected Hexagonal Boron Nitride Networked Cu-Ni Composite
Zahid Hussain, Hye-Won Yang, Byung-Sang Choi
Korean J. Met. Mater. 2021;59(7):505-513.   Published online 2021 Jun 16
DOI: https://doi.org/10.3365/KJMM.2021.59.7.505

Abstract
A three-dimensionally interconnected hexagonal boron nitride (3Di-hBN) networked Cu-Ni (3DihBN-Cu-Ni) composite was successfully synthesized in situ using a simple two-step process which involved the compaction of mixed Cu-Ni powders (70 wt.% Cu and 30 wt.% Ni) into a disc followed by metal-organic chemical vapor deposition (MOCVD) at 1000 oC. During..... More

Korean J. Met. Mater. 2019;57(1):28-37.   Published online 2018 Dec 14
DOI: https://doi.org/10.3365/KJMM.2019.57.1.28

Abstract
The hot crack resistance and mechanical properties of flux cored arc (FCA) welds were investigated with three kinds of welding consumables having different boron (B) and manganese (Mn) contents for high strength carbon steel. The hot crack resistance, measured from self-restraint testing, strongly depended on the amount of B in..... More

Study on the Water Durability of Molybdate Glasses with B<sub>2</sub>O<sub>3</sub> as Low Temperature Sealing Materials
Jae-Young Shin, Jae-Min Cha, Dae-Sung Kim, Dea-Geol Jeong, Jun-Hyeon Bae, Bong-Ki Ryu
Korean J. Met. Mater. 2017;55(12):905-910.   Published online 2017 Dec 4
DOI: https://doi.org/10.3365/KJMM.2017.55.12.905

Abstract
The boron alkali molybdate glass system was investigated as lead-free low-temperature melting sealing materials, with different boron oxide contents between 0 and 8 mol%. The glasses were characterized using X-ray diffraction (XRD), differential scanning calorimetry (DSC), infrared spectroscopy (IR), and by densities. Their chemical properties were measured by their dissolution..... More
