연소반응 합성된 TiC 분말 소결체의 미세구조에 미치는 금속 Binder 영향 = Effect of Metal Binder on the Microstructure of the TiC Cermet Sintered by Combustion Synthesis TiC Powders

다국어 초록 (Multilingual Abstract)

TiC cermets werefabricated by sintering of TiC and metal powders produced by self propagating high temperature systhesis (SHS). A total of five different cermet systems were studied. These are TiC-Ni, TiC-Co, TiC-Fe, TiC-Al and TiC-Cu. Powders of Ti, C, and metals (Ni, Co, Fe, Cu, Al) were first reacted to form TiC carbide in the matrix of each metal by SHS. The reaction products were crushed into fine powders, which were subsequently sintered at high temperatures either in hydrogen atmosphere or in vacuum for over 1 hours. The mocrosturctural evolution of the cermets was studied including carbide particle size and shape, growth of particles, and density of sintered body. The effects of different binder metals on the mocrosturctures of the cermets are discussed.
