添加碳化钛对超细Ti(C,N)-Ni金属陶瓷显微结构和力学性能的影响
EFFECT OF TITANIUM CARBIDE ADDITION ON MICROSTRUCTURE AND MECHANICAL PROPERTIES OF ULTRA-FINE Ti(C, N)-Ni CERMET
摘要
Abstract
A Ti(C, N)-based cermet with titanium carbide (TiC) additive was fabricated by the conventional powder metallurgy technique. The initial powder particle sizes of the main hard phase components [Ti(C, N), TiC and TiN] were nano/submicron-sized, in order to achieve an ultra-fine grain sizes microstructure. Through scanning electron microscopy observation, a new kind of bright core and grayish rim structure was detected, and its formation mechanism was proposed. In addition, quantitative information about the chemical composition of various phases was obtained by energy dispersive X-ray analysis. Phase identification was carried out by X-ray diffraction and the lattice parameter of each phase was calculated. The mechanical properties at room temperature were also tested, in order to correlate them with the cermet's starting composition and microstructural features.关键词
