论文摘要
分析了大型和复杂形状标本的微波烧结均匀性。提出了一种新的方法，可以通过3D打印和微波烧结来制造复杂形状的陶瓷。证明牙齿微波腔的使用可在限制晶粒生长的同时，使复杂形成成分的密集程度达到大量的致密化。通过电磁热模拟研究了微波烧结过程中处理的样品的均匀性。现象学上考虑了微波效应的现实致密性行为，包括在建模框架中。模拟表明腔体中的微波场分布之间的急剧相关性，温度曲线和样品的形状失真。
The microwave sintering homogeneity of large and complex shape specimens is analyzed. A new approach enabling the fabrication of complex shapes ceramics via 3D printing and microwave sintering is presented. The use of a dental microwave cavity is shown to enable a substantial level of densification of complex shape components while restricting the grain growth. The homogeneity of the processed samples during microwave sintering is studied by an electromagnetic-thermal-mechanical simulation. The realistic densification behavior, that phenomenologically takes into account the microwave effect, is included in the modeling framework. The simulation indicates the sharp correlation between the microwave field distribution in the cavity, the temperature profile, and the specimen's shape distortion.
