The transition layer in TiB2-GaAs and Au-TiB2-GaAs Schottky contacts
Semiconductors, 2001Spectral characteristics of the transverse bulk photovoltage in the TiB2-GaAs and Au-TiB2-GaAs Schottky contacts for starting samples (unannealed) and samples annealed at 400, 600, and 800°C were measured. The concentration of the dopant for the n-GaAs substrate was 1016 cm−3. It was found that the transition layer is formed in the TiB2-GaAs structures

The constitution diagram constructed for the quasibinary TiB2-Re system is of the eutectic type, with Teut = 2500 ± 50°K. The eutectic composition is 22 wt.% TiB2 + 78 wt.% Re. The system is characterized by small intersolubility of its components. The eutectic temperature recorded is the highest of any MeIVB2-Re system.

Oxidation Behaviour of TiB2, Al2O3-TiB2 and Si3N4-TiB2 Ceramic Systems
1992In 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

Effect of TiB2 Content on Wear Resistance of TiB2/7055 Composite Materials
2018TiB2/7055 composites with volume fractions of 0, 5.17 and 18.23% were prepared by two step method. Firstly, the Al/TiB2 master alloy was prepared by Melt Self-propagating High-temperature Synthesis method. Then, TiB2/7055 composite was prepared by adjusting the alloy elements with using this master alloy as the matrix.

Effect of sintering temperature and TiB2 content on the grain size of B4C-TiB2 composites
Materials Today Communications, 2020Abstract 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.

Abstract TiB2–25 vol% (Fe-Ni) and TiB2–30 vol% (Fe-Ni) composites with different TiB2 particle size were fabricated by vacuum pressureless sintering at 1700 °C for 1 h. The influences of TiB2 particle size on the microstructure and mechanical properties was studied in detail.
