Study on Grain Growth kinetics of Ti(C,N)-based Cermets during Sintering AITranslate
Abstract AITranslate
The sintered samples of Ti（C,N）-based cermets were prepared by vacuum sintering at different heating temperature for different holding time.The grain size was measured with metallographic quantitative method.The grain growth kinetic model of Ti（C,N）-based cermets during sintering was established based on Sellars model and Anelli model,and the grain growth kinetic equation was determined by nonlinear regression analysis of the experimental data.The results show that when the temperature is lower than1 300 ℃,the average grain size of Ti（C,N）-based cermets increases with the increase of the holding time,but the growth rate is slow.When the temperature is higher than 1 300℃,the grain growth rate rapidly increases at first to reach the maximum value and then decreases.The crystal grain growth apparent activation energy of Ti（C,N）-based cermets during sintering is 493.67 kJ/mol,and the kinetic equation is d^2.82=d^2.820＋2.75×10^23 t^ 1.373 exp[-493 670/（RT）].
