Phase Identification by EBSD Analysis of Non-Metallic Crystallites
Currently, EBSD is used routinely for phase and crystallites orientation mapping and studying the grain boundary of metallic and alloy samples [1]; this is partially due to the well-suited nature of these sample types for EBSD as they show no charging effect and can be polished smoothly to provide a good diffraction path from specimen surface back to EBSD camera. On the other hand, though not g...
متن کاملLow-Cost Impact Detection and Location for Automated Inspections of 3D Metallic Based Structures
This paper describes a new low-cost means to detect and locate mechanical impacts (collisions) on a 3D metal-based structure. We employ the simple and reasonably hypothesis that the use of a homogeneous material will allow certain details of the impact to be automatically determined by measuring the time delays of acoustic wave propagation throughout the 3D structure. The location of strategic ...
متن کاملEBSD Analysis for Microstructure Characterization of Zr-based Bulk Metallic Glass Composites
Bulk metallic glasses (BMG’s) have long been materials of interest due to their high strength, high elastic limit, wear and corrosion resistance, and ease of thermoforming above the glass transition temperature [1]. The primary technical challenge of implementing BMG’s in engineering applications is their tendency to fail catastrophically via highly localized shear banding events. Though the el...
متن کاملAutomated 3D Modeling and Analysis of Metallic Materials Using Multiple LC-SEM Images
The scanning electron microscope (SEM) has been successfully used as an analysis tool for micro scale materials in the last few decades [1]. Recently, the large chamber (LC) SEM at Y-12 has demonstrated useful results in the analysis of large specimens at nano scales. This paper summarizes the research efforts conducted by UT and Y-12 in applying state of art 3D computer vision techniques to LC...
متن کاملMetallic glassy Zr70Ni20Pd10 powders for improving the hydrogenation/dehydrogenation behavior of MgH2
Because of its low density, storage of hydrogen in the gaseous and liquids states possess technical and economic challenges. One practical solution for utilizing hydrogen in vehicles with proton-exchange fuel cells membranes is storing hydrogen in metal hydrides. Magnesium hydride (MgH2) remains the best hydrogen storage material due to its high hydrogen capacity and low cost of production. Due...
