Abstract
Hybrid organic/inorganic composites have recently been investigated in the thermoelectric field in an effort to interdependently manipulate the charge carriers, which are interconnected with electrical and thermal transport. The decoupling of a charge carrier’s roles in the hybrid structures can result in enhanced thermoelectric performance, by only exploiting the high.....

Effect of Graphene Addition on Mechanical Properties of TiN
그래핀 첨가가 TiN 기계적 성질에 미치는 영향
In-Jin Shon, Jin-Kook Yoon, Kyung-Tae Hong손인진, 윤진국, 홍경태

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.....

Abstract
A composite having 60 vol% of TiC particles was successfully fabricated by the infiltration of molten SKD11 tool steel into a TiC preform. The density of this composite was achieved to be 25% lighter than conventional steels. The penetration of the liquid metal reached geometrically complex regions without any interfacial.....

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.....

Abstract
The liners of shaped charges, a type of weapon, should possess good penetration ability and explosive power. Conventionally this is achieved by fabricating reactive Al-Ni composite layers on the Cu liners, which by themselves have fine penetration ability but poor explosive power. However, there are no studies related to the...

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,.....
