Abstract
TiB

is considered candidate materials for ultra-high temperature ceramics and cutting tools because of its a high thermal conductivity, a low coefficient of thermal expansion, a high hardness and high melting temperature. Despite these attractive properties, TiB2 applications are limited because it has a low fracture toughness below the brittle-ductile.....

Abstract
4YSZ is generally used in fuel cells, oxygen sensors, hip and knee joint replacements and thermal barriers because of it excellent properties, including low density, high biocompatibility, good resistance against corrosion, hard phase and high melting point, and high ionic conductivity. However, 4YSZ with large grain has low resistance to.....

Abstract
Aluminum nitride (AlN) has several attractive properties including high thermal conductivity, excellent electrical insulation, a thermal expansion coefficient close to that of Si and low density. Accordingly, it is considered a promising packing material and substrate for high power integrated circuits. However, its low fracture toughness at room temperature limits.....

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
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,.....
