【摘要】研究了碳热还原反应产业化制备的Ti(C1 -xNx)系固溶体粉末的组织结构特征。结果表明 ,通过控制原料成分C/Ti的准确配比 ,可产业化制备出成分优良的不同单相Ti(C1 -xNx)固溶体。粉末呈多角状和不规则形。Ti(C1 -xNx)系固溶体的点阵常数与C或N含量有很好的对应关系。通过调整粉末中元素的固溶度 ,可控制粉末的晶体结构 ,进而控制材料的性能。更多还原

【Abstract】 Microstructure of Ti(C 1-xN x) solid solution mass-produced by carbothermal reaction has been studied. The results suggest that single phase Ti(C 1-xN x) solid solution of different composition can be industrially preparated by controlling the C/Ti ratio of raw material. Powders are made up of many fine grains. They have the shape of horned and abnormal polygon. The good corresponding relationships between the lattice constant of Ti(C 1-xN x) solid solution powders and the solid solution extent of C and N elements are obtained. The crystal structure of powders and performance of cermets can be cntrolled by adjusting the solid solution extent of elements.更多还原
