Rapid Sintering of Nanocrystalline (W,Ti)C-Graphene Composites
나노구조 (W,Ti)C-Graphene 복합재료 급속소결
Seong-Eun Kim, In-Jin Shon
김성은, 손인진
Korean J. Met. Mater. 2018;56(12):854-860.   Published online 2018 Dec 5
DOI: https://doi.org/10.3365/KJMM.2018.56.12.854

Abstract
In spite of the many attractive properties of (W,Ti)C, its low fracture toughness limits its wide application. To improve the fracture toughness generally a second phase is added to fabricate a nanostructured composite. In this regard, graphene was considered as the reinforcing agent of (W,Ti)C. (W,Ti)C-graphene composites that were sintered..... More

                        
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

Abstract
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

                        
Effects of Direct Current on the Wetting between Molten Al and a Graphite Substrate
In-Jin Shon
Korean J. Met. Mater. 2018;56(7):505-510.   Published online 2018 Jul 5
DOI: https://doi.org/10.3365/KJMM.2018.56.7.505

Abstract
Graphite fiber attracted much attention in the area of aluminum based composite due to its low density and high strength. However, one of the major drawbacks in fabricating graphite reinforced metal matrix composites (MMCs) is that aluminum generally does not wet graphite. Therefore, it is difficult to impregnate the graphite..... More

                        
Sintering of a Nanostructured CoZr-ZrO2 Composite from Mechanochemically Synthesized Powders
기계화학적 합성과 나노구조 CoZr-ZrO2 복합재료 소결
In-Jin Shon, Jin-Kook Yoon, Kyung-Tae Hong
손인진, 윤진국, 홍경태
Korean J. Met. Mater. 2017;55(9):632-636.   Published online 2017 Aug 30
DOI: https://doi.org/10.3365/KJMM.2017.55.9.632

Abstract
Since their development in the 1970s ZrO2 ceramics have been shown to be promising alternative materials for total hip arthroplasty (THA) and total knee arthroplasty (TKA). However, ZrO2 is so brittle that in vivo failure can result from fracture of the ceramic femoral head and fracture of the ceramic acetabular..... More

      
Effect of Graphene Addition on Mechanical Properties of TiN
그래핀 첨가가 TiN 기계적 성질에 미치는 영향
In-Jin Shon, Jin-Kook Yoon, Kyung-Tae Hong
손인진, 윤진국, 홍경태
Korean J. Met. Mater. 2017;55(3):179-183.   Published online 2017 Mar 3
DOI: https://doi.org/10.3365/KJMM.2017.55.3.179

Abstract
Despite of many attractive properties of TiN, the current concern about the TiN focuses on its low fracture toughness below the ductile-brittle transition temperature. To improve its mechanical properties, the approach generally utilized has been the addition of a second phase to form composites and to make nanostructured materials. In..... More

      
Effect of Graphene Addition on the Mechanical Properties of TiO2
TiO2 기계적 성질에 미치는 그래핀 첨가 영향

손인진
Korean J. Met. Mater. 2017;55(2):110-114.   Published online 2017 Feb 2
DOI: https://doi.org/10.3365/KJMM.2017.55.2.110

Abstract
Despite of the many attractive properties of TiO2, its low fracture toughness limits many industrial applications. To improve its fracture toughness, the approach commonly utilized has been the addition of a second phase, to form composites, and to make nanostructured composites. In this regard, highly dense nanostructured TiO2 and TiO2-graphene..... More

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

Abstract
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

Korean J. Met. Mater. 2016;54(11):826-830.   Published online 2016 Nov 5
DOI: https://doi.org/10.3365/KJMM.2016.54.11.826

Abstract
CoTi and ZrO2 nanopowders were mechanochemically synthesized from CoTiO3 and Zr powders according to the reaction (2CoTiO3 + 3Zr → 2CoTi + 3ZrO2). The milled powders were then consolidated by pulsed current-activated sintering within two minutes under an applied pressure of 80MPa. The average hardness and fracture toughness of the..... More

DOI: https://doi.org/10.3365/KJMM.2016.54.8.566

Abstract
TiC-Co or TiC-Ni hard materials have been used for cutting tools. However, the high cost and the low hardness of Ni or Co, and the low corrosion resistance of the TiC-Ni and TiC-Co cermets have generated interest in recent years in using them as alternative binder phases. In this study,..... More
