Abstract
AlN-MgO composites with different compositions were prepared by spark plasma sintering, and the effects of their composition on their microstructure, thermal properties, and mechanical properties were systemically investigated. MgO compositions in the AlN-MgO composites were controlled from 20 to 80 wt%. The results indicated that a phase transition did not.....

https://doi.org/10.3365/KJMM.2018.56.5.406
Abstract
Industrially meaningful hydrogen production process from mixture or syngas certainly must have a cooling process, which is typically pressure swing adsorption (PSA). However, the PSA process involves an exothermic reaction during adsorption. Recently, hydrogen separation research has been in progress in order to develop a cooling process to minimize or.....

DOI:
https://doi.org/10.3365/KJMM.2017.55.3.156
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 aim of this study is to establish an optimized hot-press sintering condition for aluminum matrix composites (AMCs) by analyzing their sintered microstructure and mechanical properties. The fabricated AMCs in this study consisted of a blend of commercial Ecka Alumix 431 powder, and Al-Si/SiC

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.....

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,.....
