Synthesis and consolidation of titanium diboride

International Journal of Refractory Metals and Hard Materials, 2007
Abstract Titanium diboride (TiB2) is one of the candidate materials for high temperature structural applications and also for control rod elements in high temperature nuclear reactors. This paper presents the experimental data on the synthesis, consolidation to dense pellets and property evaluation of TiB2 carried out in laboratory scale. TiB2 powder

On the failure of shocked titanium diboride

Royal Society of London. Proceedings A. Mathematical, Physical and Engineering Sciences, 2002
The failure of brittle materials in uniaxial compressive shock loading has been the subject of extensive recent discussion. The physical interpretation of the yielding process in titanium diboride and its Hugoniot elastic limit remain poorly defined.

Vacuum sintering of titanium diboride

Soviet Powder Metallurgy and Metal Ceramics, 1970
The results obtained lead to the conclusion that, at low temperatures (up to 1100°C), the increase of contact surfaces between the titanium diboride particles is linked with surface diffusion processes. At temperatures in excess of 1800°C, the evaporation and condensation mechanism contributed appreciably toward mass transfer.

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 ...

Microstructural characterization of titanium diboride

Materials Characterization, 1993
A wide range of microstructural and microanalytical techniques has been used to follow the effects of heat treatment on a commercial sample of titanium diboride. The effects of the interplay of grain size with microchemical changes, the initial distribution of pores, and the microcracks that develop on heat treatment are demonstrated.

MORPHOLOGY OF CHEMICAL VAPOR DEPOSITED TITANIUM DIBORIDE

Journal of Crystal Growth, 1975
Titanium diboride has been chemical vapor deposited from TiCl4, BCl3, and H3 gases on a heated graphite substrate. The morphologies of the deposits were correlated with the deposition parameters of substrate temperature, total pressure, B: Ti atomic ratio, Cl: H atomic ratio, and total flow rate.

Pyrolytic Synthesis of Titanium Diboride

Journal of the American Ceramic Society, 1963
Titanium diboride was synthesized by the vaporphase reaction of the chlorides of titanium and boron on a heated substrate. Under certain described conditions, the resulting deposit was found to have a preferred atomic arrangement which could be described as alternating layers of titanium and boron atoms perpendicular to the plane of deposition.

Structural and morphological investigation of the oxidation of titanium diboride in various environments I. Oxidation of titanium diboride in air

Soviet Powder Metallurgy and Metal Ceramics, 1982
It has been established that titanium diboride experiences partial oxidation during sintering. The phase composition of the low-temperature oxidation products of titanium diboride has been determined. The intensity of oxidation is a maximum at 500°C, which is linked with a specific character of growth of oxide films on titanium diboride.

Structure and composition of titanium diboride coatings

Soviet Powder Metallurgy and Metal Ceramics, 1985
The authors present the results of metallographic and x-ray diffraction analysis of the structure and phase composition of composite titanium diboride coatings and of laboratory studies of the cutting qualities of disposable polyhedral tool tips with such coatings. They present their data in two tables and two charts.
