Microstructure Evolution of Ti(C,N)-based Cermets during Sintering AITranslate
Abstract AITranslate
Ti（C,N）-Co-Mo-WC samples were sintered in vacuum under different conditions of heating temperature and rate.The sample size was measured before and after sintering to calculate the shrinkage.Microstructure of the sample was observed with scanning electron microscopy and its density was determined with Archimedes method.Microstructure evolution rule was investigated of Ti（C,N）-based cermets during sintering.The results show that the green body expands firstly and then shrinks with the increase of sintering temperature from 1 000℃to 1 200℃,and sharply shrinks at 1 300℃.There are mainly diffusion reaction and solid solution reaction at the stage of solid phase sintering to form W and Mo-rich inner ring phase of（Ti,W,Mo）（C,N）.Liquid phase sintering at 1 300~1 500 ℃ can promote rapid densification of the cermets and form Ti-rich outer ring phase of（Mo,W,Ti）（C,N）.
