Study on Dielectric Properties of Nanostructured Composite of ZnO-La0.45Pr0.25Sr0.3MnO3 Bulk Ceramic
Abstract: In this study, nanostructured bulk composites of ZnO-La0.45Pr0.25Sr0.3MnO3 (LPSMO) were studied. These nanostructured composites were prepared by chemical solution technique. Nano particles of ZnO and LPSMO were mixed in weight ratio of 9:1 to prepare nanocomposite ceramic. Compared with pristine ZNO, nanocomposite of ZnO-LPSMO showed enhanced dielectric constant. The spin polarization (in ferromagnetic region) based quantum tunneling effect is used to explain the experimental results. Enhanced dielectric properties in nanocomposite …

Effect of Notch on Low Cycle Fatigue of AA 2024-T351
Abstract: Notch effect on low cycle fatigue of AA 2024-T351 was investigated. Decreasing notch curvature leads to less cyclic hardening. Values of fatigue strength exponent (b) and fatigue ductility (c) for notch specimens were out of range of metallic materials. The SEM examination showed multi-crack origins with secondary cracks and a large final-fracture zone for unnotched specimens, while there was small final fracture zone close to the center of the specimen …
