Effect of sintering temperature and TiB2 content on the grain size of B4C-TiB2 composites

Materials Today Communications, 2020
Abstract Boron carbide (B4C) is a ceramic with great properties such as low density, the third hardness after diamond and cubic BN. However, it is a limited use cause of its poor sinterability and low fracture toughness. Titanium diboride (TiB2) has been used as an ideal additive to get B4C ceramics with good properties.

Oxidation Behaviour of TiB2, Al2O3-TiB2 and Si3N4-TiB2 Ceramic Systems

1992
In view of the susceptibility of TiB2 to oxidation, the thermal stability of monolithic TiB2 and of Al2O3-30 vol% TiB2 and Si3N4-20 vol% TiB2 composites was investigated. The temperature at which TiB2 ceramic starts to oxidize is about 400°C, oxidation kinetics being controlled by diffusion up toT?900°C and in the first stage of the oxidation at 1000°C

Mechanical and tribological properties of TiB2-SiC and TiB2-SiC-GNPs ceramic composites

Journal of the European Ceramic Society, 2020
Abstract TiB2-SiC and TiB2-SiC-graphene nanoplatelets (GNPs) composites were prepared using field-assisted sintering technology at 2100 °C in argon atmosphere, and the influence of the SiC and different GNPs addition on microstructure development, mechanical and tribological properties has been investigated.

High Strength TiB2

2008
It was described in a previous paper that fully dense TiB2-20 wt pct sintered bodies were fabricated by glass encapsulation HIP, and their three-point bending strength was as high as 1200 MPa. In this material, grain growth occurred during sintering; the grain sizes of TiB2 and ZrO2 in a sintered (HIP'd) body were 4-6 microns and 2-5 microns ...

Effect of TiB2 Particle Size on Erosion Behavior of Ag-4wt% TiB2 Composite

Rare Metal Materials and Engineering, 2015
Abstract In order to clarify the effect of TiB 2 particle size on the arc erosion behavior of Ag-TiB 2 composite, Ag-4wt%TiB 2 composite reinforced by different grain-sized TiB 2 particles was prepared by mechanical milling and powder metallurgy.

Influence of TiB2 content and powder size on the dielectric property of TiB2/Al2O3 composites

Scripta Materialia, 2009
TiB2/Al2O3 composites were prepared by hot-pressed sintering using TiB2 and Al2O3 powders. The dielectric property of these composites was investigated. The mechanisms of polarization and microwave energy loss were discussed. Both the real part of dielectric constant and the energy loss increase greatly with increasing TiB2 content over the frequency ...
