Effect of BN Addition on the Mechanical Properties of TiN-BN Composites
Woo-Jin Cho, In-Jin Shon
Korean J. Met. Mater. 2018;56(9):658-663.   Published online 2018 Sep 5
DOI: https://doi.org/10.3365/KJMM.2018.56.9.658

Titanium nitride (TiN) has been used extensively in coating materials and cutting tools because of its attractive properties, which include low density, high melting point, high hardness and thermodynamic stability. However, like many ceramic materials, its low fracture toughness limits wide industrial application. The methods generally utilized to improve its..... More

Rapid Sintering of Nanocrystalline SiC-Graphene Composites
나노구조 SiC-Graphene 복합재료 급속소결
In-Jin Shon
Korean J. Met. Mater. 2016;54(12):893-898.   Published online 2016 Dec 5
DOI: https://doi.org/10.3365/KJMM.2016.54.12.893

The low mechanical properties of SiC limit its wide application despite many attractive properties. To improve the mechanical properties, a second phase has been generally added to make a nanostructured composite. In this respect, graphene was evaluated as the reinforcing agent of SiC. SiC-graphene composites were sintered within 2 min..... More

Catalytic Activity and Surface Characteristics of WO<sub>3</sub>-doped MnO<sub>x</sub>-TiO<sub>2</sub> Catalysts for Low-temperature Selective Catalytic Reduction of NO<sub>x</sub> with NH<sub>3</sub>
Byeongkil Shin, Heesoo Lee, Hyun Park
Korean J. Met. Mater. 2016;54(10):787-792.   Published online 2016 Oct 5
DOI: https://doi.org/10.3365/KJMM.2016.54.10.787
The effect of added WO3 on the catalytic activity and surface characteristics of the MnOx-TiO2 system was investigated for the low-temperature selective catalytic reduction of NOx with NH3. Based on physio-chemical characterizations, the specific surface areas of the WO3-MnOx-TiO2 catalysts increased from 76.12 m2/g to 90.29 m2/g as the WO3... More
Materials Analysis & Characterization
Transmission Electron Microscopic Analysis of Micro-Twin
미세쌍정의 투과전자현미경 해석
Kun Kul Ryoo, Mi-young Ha, Kang Deuk Lee
류근걸, 하미영, 이강득
Korean J. Met. Mater. 2016;54(9):711-715.   Published online 2016 Sep 5
DOI: https://doi.org/10.3365/KJMM.2016.54.9.711

Micro-twinning has been investigated in some state-of-the-art materials by transmission electron microscopy, but such characterizations have not been clear so far. Micro-twins must be characterized by identifying their spots in the electron diffraction pattern, which is very unique compared to normal defects such as dislocations or stacking..... More
