应材料科学与工程学院孙旭东教授和李晓东教授的邀请，日本国立材料科学研究所（National Institute for Materials Science，NIMS）功能材料研究中心主席研究员Byung-Nam Kim来我院进行学术访问，并于10月23日10:00在知行楼424做学术报告，欢迎各位老师和同学参加。
报告时间：10月23日（周一）10:00-12:00
报告地点：知行楼424会议室
报告题目：Analysis of Densification Kinetics during Sintering of Zirconia
报告简介：In this study, a method is proposed to determine the unspecified density function during isothermal sintering of Y2O3-stabilized zirconia. The densification kinetics and the grain growth during the isothermal sintering were examined at various temperatures by using a dilatometer. An interesting point is that the relationship between the grain sizeGand the relative densityDis not constant but dependent on the temperature, though a constant relationship has widely been recognized. With increasing temperature, the density-dependence of the grain size decreases in the intermediate stage, whereas it increases in the final stage. Using the temperature-dependentG-Drelationship, the unspecified density function was determined in the intermediate and final stages.
