Abstract To satisfy the most stringent criteria in terms of new cardiovascular stents, pure Zn was alloyed with 1 wt pct Mg and subsequently subjected to plastic deformation, using conventional hot extrusion followed by multi-pass hydrostatic extrusion. A detailed microstructural textural characterization obtained materials conducted, mechanical properties were assessed at each pass deformation process. In contrast Zn, hydrostatically extruded low-alloyed is characterized a remarkable...
The mechanical properties such as compressive strength and nanohardness were investigated for Pinctada margaritifera mollusk shells. was evaluated through a uniaxial static compression test performed along the load directions parallel perpendicular to shell axis, respectively, while hardness Young modulus measured using nanoindentation. In order observe crack propagation, first time material, in-situ X-ray microscopy (nano-XCT) imaging (together with 3D reconstruction based on acquired...
The marine composites market is driven by the increasing demand for lightweight, corrosion-resistant, and impact-resistant boats. Polymer matrix are currently most popular composite material in applications. Fiberglass practically main type of fiber that used extensively Due to aggressive sea environment, structural elements ships exposed damage due phenomenon osmosis. This also favored defects result from impacts technological errors during production these elements. Non-destructive testing...
Controlled growth of hydroxyapatite (HAp) coatings on titanium substrate plays an important role in the fabrication composites for bone tissue engineering. We describe synthesis crystalline Ti/TiO2 through a hydrothermal method by using ethylenediamine tetraacetic acid disodium salt (Na2EDTA) and varying concentrations ammonium hydroxide (NH4OH) calcium-phosphate precursor solution. Na2EDTA serves as chelating agent, while NH4OH is used alkaline source crystal modifier. characterized HAp...
Abstract This paper presents the ability of Terahertz (THz) radiation in non-destructive testing composite materials used for military applications ballistic protections. The terahertz scanner was to detect defects selected elements consisting aramid fiber-reinforced composites. Two sources radiation, operated at frequencies 100 GHz and 300 GHz, were chosen. results next compared with one obtained via X-ray imaging. preliminary showed that THz has high potential as detection method these...
Alumina ceramics are widely used in the military as a component of ballistic covers due to their high number mechanical properties such strength, hardness, and wear resistance. However, alumina exhibits brittle fracture behavior which may lead catastrophic failure construction. Due that, it needs be monitored during its lifetime. Thus, non-destructive testing methods very important ensure safe reliable use these elements through non-invasive, contactless monitoring. In frame this work,...
The reinforcement function of shell ribs depends not only on their vaulted morphology but also microstructure. They are part the outer layer which, in case Pinna nobilis bivalve, is built from almost monocrystalline calcitic prisms, always oriented perpendicular to growth surfaces. Originally, prisms and c-axes follow radii rib curvature, becoming oblique thickness direction. Later, bend reach nacre perpendicularly, retain initial orientation. Calcite grains form nonrandom boundaries. Most...
The unique properties of Terahertz (THz) radiation include among others the ability to penetrate through electrical insulators such as ceramics, plastics, or plastic composites. Because that, it is possible non-destructively and contact free analyze materials with internal cavities both in transmission reflection configuration. commercially available low-power sources provide results which quality still beyond expectations. As a result, efforts are being made resolve studies' focused on...
Fiber-reinforced composites are materials that increasingly replacing metals in many construction solutions. Damage to the composite structure may occur both as a result of technological errors production phase and during operation material fatigue or an impact by foreign body. The specificity defects fiberreinforced results development non-destructive testing methods enable detection these defects. One is use terahertz radiation. Terahertz radiation penetrates well through non-metallic...
With regards to composite materials, the need for noninvasive evaluation of their structures, components, or systems they form continues rise. It relates fact that composites, due two-phased (at least) composition, are vulnerable different damages arising during manufacturing use. Thus, there is a non-destructively monitor such materials especially when used in safety applications as e.g., bulletproof vests and damage may pose real threat. In frame this work, use newly developed...
With regards to composites, the need for non-destructive evaluation (NDE) of their inner structure, or constructions they form continuously rises. Nowadays, a great deal attention has been paid methods based on use Terahertz radiation (THz). It is related exceptional properties THz which allows contactless, safe, and fast inspection non-conductive materials. In frame this work results imaging method, operated at frequency 300 GHz, are presented. The selected aramid fiber-reinforced...
Composites are materials that have replaced traditional construction in numerous applications various fields. Due to the possibility of creating required material properties, fiber-reinforced composites most often used. Despite competition from carbon and aramid fibers, earliest glass fibers produced used many applications. One areas where fiber reinforced (GFRP) make a significant contribution structural is aviation. Because both during production operation, exposed damage, which occurs...
The non-destructive testing methods (NDT) are gaining significant attention due to their ability monitor the objects structure without causing damage. In recent years, studies focused on NDT have been directed towards imaging with use of terahertz (THz) waves. presented study describes imaging-based method and results selected military-designated materials intentionally introduced defects. main aim work was clearly detect various discontinuities in interior thus, show possibilities newly...
