STUDY OF Ti plus C COMBUSTION SYNTHESIS REACTION IN A CONTROLLED DECLINING TEMPERATURE STATE
The purpose of this article is to synthesize a Ti-C system under a known cooling rate by applying a secondary hybrid system in the form of semi-reacted titanium carbide. The synthesis reaction is performed in a hot, inert, shielded crucible. The portions of reacting and interacting materials are determined using the Rietveld phase quantification method. The product microstructure is studied, and the nanomechanical properties are measured via a nanoindentation technique. The experimental results revealed that the reaction behavior and mechanical properties of Ti+C elemental powder were initiated at a particular temperature level. At 2610 degrees C, the titanium carbide phase formed 14% of the compound composition, with 65 GPa Young's modulus and 563 MPa hardness.
