不同晶粒生长轨迹的主烧结曲线：MgAl2O4的实例研究
Master sintering curve with dissimilar grain growth trajectories: A case study on MgAl2O4
摘要：
烧结是制备高性能陶瓷的关键步骤。密度和晶粒尺寸对陶瓷烧结动力学和最终材料性能起着至关重要的作用。主烧结曲线（MSC）是用于探索烧结模型动力学的众所周知的工具。然而，传统的MSC理论假设一个独特的烧结轨迹，而我们的研究MgAl2O4尖晶石显示不同的生长响应。Park的MSC理论已被应用，并与传统的MSC方法相比，获得激活能与不相似的晶粒生长轨迹。
英文摘要：
Sintering is a key step in the processing of high performance ceramics. Both the density and the grain size play a crucial role on the ceramic sintering kinetics and the final material properties. The master sintering curve (MSC) is a well-known tool for exploring sintering models kinetics. However, the conventional MSC theory assumes a unique sintering trajectory, while our study on MgAl2O4 spinel shows dissimilar growth response. Park's MSC theory has been applied and compared with the conventional MSC approach for obtaining the activation energy with and without dissimilar grain growth trajectories.
