Y-TZP纳米级粉料烧结初期动力学模型的探讨

KINETIC MODEL FOR THE INITIAL STAGE OF SINTERING OF Y-TZP NANOMETER POWDER

通过对Y-TZP纳米级粉料烧结初期动力学过程的研究,提出了晶界扩展是烧结初期导致收缩的主导因素,推导了相应的烧结动力学方程。

Based on the kinetics of the initial stage of sintering of Y-TZP nanometer powder, theoretical model and kinetic equations are proposed in the paper.The results obtained by these equations are in good agreement with the experimental results.
