A dynamic transmission electron microscope (DTEM) has been designed and implemented to study structural dynamics in condensed matter systems. The DTEM is a conventional situ (TEM) modified drive material processes with nanosecond laser, “pump” pulse measure it shortly afterward 30-ns-long probe of ∼107 electrons. An image resolution <20nm may be obtained single pulse, largely eliminating the need average multiple measurements enabling unique, irreversible events nanosecond-...
Properties of fragmentation from an explosively driven 316L stainless steel spherical shell section fabricated by a laser powder bed additive manufacturing process with minimal surface finishing are investigated. This is insensitive high explosive, resulting in strain rate deformation (>8 × 103 s−1) and failure the steel. Photonic Doppler velocimetry measures expansion rate; dynamic radiography high-speed imaging capture fracture behavior The response additively manufactured compared...
High-purity tantalum single crystal cylinders oriented with [011] parallel to the cylinder axis were deformed 10, 20, and 30 percent in compression. The samples took on an ellipsoidal shape during testing, elongated along [100] direction almost no dimensional change [011]. Two orthogonal sectioning planes selected for characterization using Orientation Imaging Microscopy (OIM): one plane containing (longitudinal) other (transverse). OIM revealed patterns of alternating rotations that develop...

We consider the nature of faults in dissociated 9R phase at an incoherent twin boundary copper. Analysis dislocation content a five-layer break normal ABC/BCA/CAB stacking sequence shows that this defect is associated with secondary grain (SGBD) Burgers vector a/6[211]. Atomistic simulations SGBDs interface show sign important to determining core structure dislocation. The resulting atomistic structures and width fault can be directly understood by analyzing set twinning dislocations make up...

The authors present some important technical advantages that can be realized by implementing fiber optics aboard ships. They emphasize the problem of cable clutter ships and weight reduction gained through copper cables. also describe a new shipboard fiber-optic series designed to meet recently published US Navy specifications.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
