层析重建技术在生坯密度分析中的应用
Application of Tomographic Reconstruction Techniques for Density Analysis of Green Bodies
摘要：
陶瓷制造以及烧结金属制造的进展在很大程度上依赖于生坯密度分布的评估。从许多角度来看，这种评估是至关重要的，包括致密化过程的\textit{in-silico}模拟的本构模型的校准。为此，X射线断层扫描和其他技术是可能的，但对一些机构来说可能无法管理。因此，在本文中介绍了一种破坏性的方法来测量密度场的生坯样品使用数控铣床，分析天平，和分析技术从计算断层扫描领域。一个虚拟的实验中，该方法被用来重建一个模拟的生坯密度场，并发现令人满意地对应于原始的解决方案。用该方法计算了氧化铝粉末截顶圆柱体的生坯密度场，并给出了重构后的密度场。
英文摘要：
Progress in the manufacturing of ceramics, but also of sintered metals, strongly relies on the evaluation of the density distribution in green bodies. This evaluation is crucial from many points of view, including the calibration of constitutive models for \textit{in-silico} simulation of densification processes. To this end, X-ray tomography and other techniques are possible but can be unmanageable for some institutions. Therefore, a destructive method is introduced in the present article to measure the density field of a green body sample using a CNC mill, an analytical balance, and analysis techniques from the field of computational tomography. A virtual experiment is presented where the method is used to reconstruct a simulated green body density field and is found to satisfactorily correspond to the original solution. The green body density field of a truncated cylinder made of alumina powder is evaluated using this method and the reconstructed field is presented.
