Microstructure and hardness of TiB2

, 2012
MICROSTRUCTURE AND HARDNESS OF TIB2 TiB2 in its pure form is extremely hard material with high melting point. This behaviour predetermines it to be used as e.g. nozzles, armour or wear parts.

Electronic Structure and Chemical Bond of TiB2-Al2O3 Composite

, 2011
TiB2-Al2O3 composite was studied by the first principle method. Ti maintains a high positive charge and O increases more charge (absolute value) in the interface, so there is strong ionic interaction among the ions in the interface of TiB2-Al2O3 ...

Characterization of TiB2-AlN composites for application as cutting tool

, 2018
Densified ceramic TiB2-AlN composites were prepared by spark plasma sintering and samples were subjected to short time machining tests. The maximum relative density and toughness were 96.9% and 16.2 GPa, respectively. Composites with 70 wt% AlN and 70 wt%

Planar shock compression of spark plasma sintered B4C and B4C–TiB2 ceramic composites

AIP Advances
Blending of ceramic constituent phases enhances sinterability and performance in high strength ceramics. Here, a near fully dense blended boron carbide (B4C)–titanium diboride (TiB2) composite produced through spark plasma sintering (SPS) is probed to ...

Effect of TiB2/TiC ratio on the microstructure and mechanical properties of high volume fractions of TiB2/TiC reinforced Fe matrix composite

, 2013
Dense high volume fractions of different molar TiB2/TiC ratios reinforced Fe matrix composite were successfully fabricated through the SHS reaction assisted with pressure. The reaction mechanisms for three systems were dissolution–precipitation. The TiB2

Synthesis of nanostructured Fe–TiB2 composites with excellent mechanical properties via laser powder bed fusion

Journal of Materials Research and Technology
The mechanical performance of Fe–TiB2 composites produced via conventional methods is limited by inadequate microstructure refinement, thereby restricting their application in high modulus steels (HMSs).
