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

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

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

Fabrication and Mechanical Properties of Nanostructured TiC-TiAl by the Pulsed Current Activated Sintering
펄스전류 활성 소결에 의한 나노구조 TiC-TiAl 제조 및 기계적 성질
Bong-Won Kwak, Byung-Su Kim, Jin-Kook Yoon, Kyung-Tae Hong, In-Jin Shon
곽봉원, 김병수, 윤진국, 홍경태, 손인진
Korean J. Met. Mater. 2016;54(8):566-572.   Published online 2016 Aug 5
DOI: https://doi.org/10.3365/KJMM.2016.54.8.566

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
