基于元胞自动机的陶瓷复合材料的设计与制备

Design and fabrication of ceramic composites based on the cellular automata

基于元胞自动机理论对ZrB2/(W,Ti)C陶瓷复合材料进行了模拟,并对其进行了相关实验验证。模拟结果表明,随着(W,Ti)C含量的增加,晶粒的形貌不断地发生演化,(W,Ti)C加入的比例较合理时晶粒大小合适并分布比较均匀。实验结果表明,晶粒的尺寸随模拟的变化规律与实际情况较为吻合,利用元胞自动机理论进行复合材料的模拟,可以很好地模拟复合材料的微观组织演化。

The simulation of the microstructure for ZrB2/（W,Ti）C composite materials based on the cellular automata theory and related experiments were presented.The simulation results showed that the morphology of the grain was changed with the increases of（W,Ti）C content.The grain size distribution is more suitable and homogeneous in the composite with a reasonable（W,Ti） C proportion.The test results showed that the changing rule of simulation basically agree with the test data.Simulation of composite materials based on the cellular automata theory can achieve good effect for the microstructure evolution.
