摘要

在这项工作中，我们对一种由镁、铜和钨带铸造而成的阻抗梯度冲击器进行了超声测量。我们还破坏性地从零件中提取小的代表性样品，用于x射线计算机断层扫描的补充表征。结合这两个数据集，可以将一些测量的超声特征直接分配给x射线断层扫描识别的特定材料特征。我们的研究结果表明，在x射线计算机断层扫描的指导下，超声检查可以用来识别亚毫米级材料的合并和空间异质性。

Ultrasound and X-ray Cross-Characterization of a Graded Impedance Impactor used for Shock-Ramp Compression Experiments

Abstract In this work we perform ultrasound measurements on an impedance graded impactor made by tape casting magnesium, copper, and tungsten. We also destructively extract small representative samples from the part for complementary characterization with x-ray computed tomography. Combining the two data sets enables direct assignment of some of the measured ultrasound features to specific material characteristics identified by x-ray tomography. Our results demonstrate how ultrasound inspection, informed by x-ray computed tomography, can be used to identify sub-millimeter material amalgamations and spatial heterogeneities in this graded material.

期刊介绍： Sensing and Imaging: An International Journal publishes peer-reviewed theoretical and experimental papers in print and online covering sensing and imaging techniques, systems, networks, and applications in engineering, science and medicine. The journal scope is broad and multidisciplinary, covering subsurface and surface sensing, and other sensing areas. Subsurface and surface sensing involves detection, identification and classification of objects, structures and matter, respectively, under and at surfaces.
