Combustion Synthesis of Titanium-Tungsten Carbide Composites in Iron Matrix
Combustion synthesis has been used to produce Fe-(Ti,W)C composites. A simple reactor was designed which made it possible to ignite the samples under controlled atmosphere. Samples with different W/Ti ratio were ingnited under argon atmosphere by an electric arc and a self-propagating reaction was initiated in each sample. Different composites such as WC in Fe-Ti matrix, WC+(Ti,W)C in Fe matrix...

متن کاملKINETIC STUDY OF SYNTHESIS OF TITANIUM CARBIDE BY METHANOTHERMALREDUCTION OFTITANIUM DIOXIDE
Abstract: Reduction of the Titanium dioxide, TiO2, by methane was investigated in this work. The thermodynamic of reaction was examined and found favorable. The reaction of titanium dioxide with methane was carried out in the temperature range 1150°C to 1450°C at atmospheric pressure with industrial high porosity pellets prepared from titanium dioxide powder. The evolved gas analyzing method wa...
متن کاملEFFECT OF MECHANICAL ACTIVATION ON CARBOTHERMIC SYNTHESIS OF TITANIUM CARBIDE FROM ILMENITE CONCENTRATE
The synthesis of advanced materials from low cost minerals concentrates is a new field of study that has great potential applications. In this paper, the effect of milling time on the temperature of initiation and amount of carbothermic reduction of ilmenite has been investigated. The stoichiometric molar ratio (1:4) of ilmenite to graphite was mixed and mechanically activatedfor 30-70 hours at...
