Micro-CT has become widely used to analyze and test additively manufactured parts, particularly for porosity analysis and dimensional measurement. In conventional manufacturing, a weld would always be inspected for voids and inclusions, but in additive manufacturing the entire sample is essentially one large weld. Therefore, to qualify and verify safety-critical aerospace, automotive, …
Fiber characterization and orientation analysis Fibrous structures occur frequently in both natural and synthetic materials. With micro-CT, it is possible to analyze individual fiber properties (such as diameter), and orientation distribution. With several software tools, in-depth geometric characterization of fibers is possible. “The interface between fiber and matrix material in composites and …
Fiber-reinforced plastics (or polymers) are composite materials made of a polymer matrix that is reinforced with fibers. Typically, most of these composites have strong, stiff fibers in a matrix, which produces a component that often has a low density yet is strong and stiff. Fibers, such as glass (as in fiberglass), carbon, …
Comparison of medical and industrial X-ray computed tomography for non-destructive testing Industrial micro-CT scanning is a laboratory-based non-destructive testing technique used in a variety of applications for samples ranging from 1mm to typicallty about 300mm in diameter. Micro-CT scanners are used for industrial non-destructive testing due to the superior resolution possible compared …
Modern Forensics Reveal Gruesome Details Of King Richard III’s Death ABSTRACT Richard III was buried in haste in 1485 after he was killed in battle and the whereabouts of his remains were unknown for centuries. In 2012, a skeleton was excavated from the former site of the Church of the Greyfriars in …
One of the most intriguing and historic forensic examinations of a human skull was that of King Richard III’s, the last king of the House of York and the last of the Plantagenet dynasty. King Richard III’s death in the final battle of the Wars of the Roses marked the end of …
Examining the internal structure of archaeological artifacts can provide unique insights that can help us understand the people who made them, their culture, and the technology they developed to shape the world around them. Archaeometry, or the application of scientific techniques to the analysis of archaeological artifacts, is transforming modern archaeology and …
Quantifying the degradation of degradable implants and bone formation in the femoral condyle using micro‑CT 3D reconstruction ABSTRACT Degradation or corrosion negatively affects magnesium alloys but previous evaluation methods for non‑traumatic in vivo quantification of implant degradation and bone formation have been imperfect. In this study, degradation was monitored by weighing the …
Corrosion in metals can affect a wide array of man-made materials, from reinforced steel in concrete to historic monuments and implanted medical devices. Corrosion causes a loss of strength that can lead to safety hazards in bridges, buildings, and pipelines, as well as in medical devices. The annual direct cost of metallic …
Micro-Computed Tomography Measurements in Electronics ABSTRACT Previous methods of measuring deformations in electronic components and assemblies usually involved optical methods, which required cross-sectioning of the part to have access to the region of interest. Additionally, the measurements could be limited to the line of sight so that only the optically visible cut …
