Sintering dilatometry based grain growth assessment

Charles Manière, Shirley Chan, Geuntak Lee, Joanna Mckittrick, Eugene A. Olevsky

摘要:

体积收缩、晶粒长大以及它们之间的相互作用是陶瓷自由烧结过程中发生的主要事件。这两种现象都影响着高温烧结法的曲线。结果表明,烧结的连续介质理论可以利用的格式,使提取的最大量的信息的致密化和晶粒生长动力学的基础上一个简单的crackometry测试。我们在这里提出的能力,这样一个快速的方法(基于膨胀法的晶粒生长评估DGA)用于氧化锆的烧结和晶粒生长的建模。

英文摘要:

Volume shrinkage, grain growth, and their interaction are major events occurring during free sintering of ceramics. A high temperature sintering dilatometry curve is influenced by these both phenomena. It is shown that the continuum theory of sintering can be utilized in the format enabling the extraction of the maximum amount of information on the densification and grain growth kinetics based on a simple dilatometry test. We present here the capability of such a fast approach (Dilatometry based Grain growth Assessment DGA) utilized for the modeling of sintering and grain growth of zirconia.
