Titanium Nitride and Titanium Carbide as Semiconductors
Nature, 1954IT is well known that titanium nitride shows the electric properties of a typical metal1. In fact, the specific resistivity ρ is lower than that of titanium metal itself. We have re-examined these experiments, using van Arkels's technique2 of deposition from the vapour phase for the preparation.

Titanium carbide-based carbide steels made of chips of titanium alloys
Soviet Powder Metallurgy and Metal Ceramics, 1992Properties and microstructure of carbide steels produced on the basis of titanium carbide are studied. Powdered TiC was obtained from chip wastes of the titanium alloys VT1-0, VT20, VT3-1, VT25, VT5-1, and OT4-1 in three ways: nitridingcarbidizing, double carbidizing, and oxidizing-carbidizing.

AbstractA recent methodfor estimating the cohesion of transition metal carbides with the NaCl type structure is applied to the ordered forms of non-stoichiometric titanium carbide. It is concluded that the ordering occurs because the arrangement of Ti–Ti nearest neighbour links is better able, when regular, to accommodate a redistribution of dd bonding

JOM, 1952
A pressure-sintering method was used to produce binder-free and very dense TiC specimens. Some physical properties of these TiC bodies were determined and found to compare favorably with those of certain cemented TiC grades. It was also observed that the hot transverse rupture strength of TiC bodies remained substantially the same regardless of the ...

Surface Science Spectra, 1994
The Auger electron spectra for titanium carbide are presented. The first derivative Auger electron spectrum for the C KLL line is characteristic of a carbide. The differentiated C KLL peak contains three components present at the approximate kinetic energies of 250, 260, and 270 eV, with the peak at 270 eV having a greater intensity in the positive ...

AbstractGuided by the results and concepts of band theory and tight binding theory, a simple model of cohesion in TiCx and related compounds is proposed, in which each carbon atom claims four d electrons from its transition metal neighbours to form saturated covalent bonds; and in which any d electrons surplus to this are used to form metal–metal ...

1. A study was made of conditions of preparation of titanium carbide-Kh12M steel (30 and 50 wt.%) alloys at various titanium carbide compositions (combined carbon contents ranging from 14.4 to 19.1 wt.%). 2. It was established that the sintering of alloys with a carbon-deficient titanium carbide brings about impregnation of the latter ...

Cermet plasma coatings with titanium carbide
Physics and Chemistry of Materials Treatment, 2018High-grade iron S27 alloy and cermet S27 + 50 vol % TiC are sprayed in Ar-N2 plasma with local protection from the air with a nozzle application. Under S27 alloy spraying, the oxygen content in the coating increases from 0.32 to 0.98%, the nitrogen content increases from 0.038 to 0.15%, and the carbon content is reduced from 4.26 to 3.47%.

The thermal conductivity of titanium carbide, zirconium carbide, and titanium nitride was measured by a variety of techniques in the temperature range 200° to 2000° C. The titanium nitride results are a factor of four higher than the previously published values at 1000°C and show a positive temperature coefficient for the thermal conductivity rather ...

The influence of variations in the titanium carbide (TiC) content employed during spark plasma sintering (SPS) of nickel–titanium carbide (Ni-TiC) composites on its microstructure and mechanical properties has been investigated systematically. Mechanical alloying (MA) uses a technique of cold welding and repetitive fracturing of composite powder to ...
