Dislocations in titanium diboride

Philosophical Magazine A, 1991
Abstract In this investigation, it was shown that titanium diboride would plastically deform at a temperature of 1273 K and at a stress level much lower than predicted by previous experimental data. The crystal structure of titanium diboride is a topologically hexagonal structure which allows for a number of possible slip systems.

Corrosion of titanium diboride

Journal of the Less Common Metals, 1975
Abstract The corrosion resistance of pressed and sintered (PAS) titanium diboride has been compared with that of electrodeposited titanium diboride. Anodic polarization studies in 0.5 M sulfuric acid showed that PAS titanium diboride corrodes at rates of 50 to 100 times greater than electrodeposited titanium diboride.

The oxidation of titanium diboride and zirconium diboride at high temperatures

Journal of the Less Common Metals, 1968
Abstract Powdered and compacted TiB2 have been heated in oxygen at pressures of 760–200 mm Hg. The TiB2-O2 reaction rate is parabolic except near 950 °C where it is cubic. The activation energy below 950 °C is 45 kcal/mole and above 950 °C is 31 kcal/mole.

Fracture in Titanium Diboride

Physica Status Solidi (a), 1989
Transmission electron microscopy is used to examine the structure of shock-loaded titanium diboride. At a shock pressure of 1.7 GPa, fracture occurs by the nucleation and splitting of b = [001] dislocation loops in the basal plane. The tensile stress of the shock pulse opens the dislocation loops into microcracks.

Reactive sputtering of titanium diboride and titanium disilicide

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1997
Nanocomposite films of titanium nitride in either boron nitride or silicon nitride matrices were prepared by reactive sputtering of titanium diboride or titanium disilicide targets in a nitrogen plasma. These films were expected to have high dielectric constants and in the case of the silicon nitride matrix high hardness.

Preparation of titanium diboride nanopowder

Inorganic Materials, 2010
We have studied the reaction between NaBH4 and TiCl4 at elevated temperatures in the range 570–1020 K and pressures of up to 10 MPa, with no solvent. The results indicate that nanoparticulate titanium diboride forms at temperatures above 820 K. According to electron microscopy data, the titanium diboride powder obtained at 1020 K consists of spherical ...
