abstract

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, and (ti, w)c in iron matrix were produced by changing w/ti ratio in the starting materials. examination of the microstructure revealed that wc had an angular morphology while (ti, w)c particles were spherical.

Combustion Synthesis of Silicon Carbide

Combustion synthesis (CS) is an effective technique to produce a wide variety of advanced materials that include powders and net shape products of ceramics, intermetallics, composites and functionally graded materials. This method was discovered in the beginning of 1970's in the former Soviet Union (Merzhanov & Borovinskaya, 1972), and the development of this technique has led to the appearance...

Synthesis of Titanium Carbide by the Combustion of TiO2-2Mg-C and 3TiO2-4Al-3C Systems in a Tubular Furnace

The combustion process of TiO2- 2Mg- C and 3TiO2-4Al-3C systems in a tubular furnace was investigated. TiC has been synthesized by the magnesiothermic reaction from a mixture of compacted powders of TiO2, Mg and charcoal as starting materials in the presence and absence of NaCl. The effects of temperature, pressure, and the stoichiometry ratio in the reactio...

Evaluation of titanium carbide metal matrix composites deposited via laser cladding

Metal matrix composites have been widely studied in terms of abrasion resistance, but a particular material system may behave differently as particle size, morphology, composition, and distribution of the hardening phase varies. The purpose of this thesis was to understand the mechanical and microstructural effects of combining titanium carbide with 431 series stainless steel to create a unique...
