Nanocrystalline Cu0.5Zn0.5AlxFe2−xO2 (x=0.0, 0.1, 0.2, 0.3, 0.4, and 0.5) ferrite materials were synthesized using standard solid state reaction technique. The effects of Al3+ contents on the structural, electrical, magnetic properties investigated. Single phase cubic spinel structure was revealed by X-ray diffraction analysis. crystallite size evaluated considering most intense peak (311) Scherrer formula. Lattice constant decreased, whereas porosity increased with increase in...
As alternative immobilization materials for Pu‐bearing nuclear waste, lead‐containing glass matrix composites with homogeneously distributed lanthanum zirconate pyrochlore particles (up to 30 % by volume) have been developed. Fabrication hot pressing at the relatively mild temperature of 610 °C leaves structure La unchanged, which is crucial containment radioactive nuclei. The Figure, an SEM image a polished sample 2 Zr O 7 , demonstrates homogeneous particle distribution and absence pores.
The applicability of electrophoretic deposition (EPD) for the fabrication single layer and multilayer ceramic coatings on dense composite materials has been examined. Al2O3/Y-tetragonal zirconia polycrystal (TZP) functionally graded composites tubular shape were successfully coated with a two coating comprising porous alumina reaction bonded mullite layers. dual structure was designed to eliminate numerous cracks caused by volume shrinkage during sintering individual EPD formed In another...
Six alloys of Fe65Ni35−x Cu x (x = 0, 0.2, 0.6, 1, 1.4, 1.8 at.%) have been prepared by conventional arc-melting technique and characterized utilizing high temperature x-ray diffraction (HTXRD) at a range from room to 773 K for determination phase, lattice parameter (a), coefficient thermal expansion (α(T)), mean square amplitude vibration ( characteristic Debye (ΘD), electrical resistivity (ρ) conductivity (κ). The studies showed that these form face centered cubic structure (fcc)...
With the industrial revolution in electronics, demand for lithium-ion batteries, particularly those designed electric vehicles and energy storage systems, has accelerated recent years. This continuously increasing requires high-performance electrode materials, as commonly used graphite anodes show limited lithium intercalation. In this context, Ni-substituted ZnCo2O4 nanostructures, thanks to their high capacity, have potential use an anode material batteries. Structural analysis concludes...
Abstract Two alloys of varying contents tantalum (Ta) and tin (Sn) were prepared homogenized to evaluate their microstructural electrochemical characteristics. The features revealed through optical microscopy X‐ray diffraction methods. formation stability passive film was studied by open circuit potential, potentiodynamic polarization scratch tests. impedance spectroscopy results simulated with equivalent electrical suggested bilayer structure outer porous inner barrier oxide films....
The structure and thermal parameters of the alloy Ni88.6Cr11.4 have been studied by an in-situ x-ray diffraction technique. experiments show that has a single phase with fcc (A1) structure, boundary which extends beyond 1050 K. No evidence formation ordered structures was found. temperature factor found to be independent static displacements. mean linear expansion does not follow classical Gruneisen relationship. Further, addition Cr into Ni leads increase in value characteristic Debye ΘD,...
AbstractAbstractDifferential thermal analysis and dilatometry investigations of Fe–Gd alloys in the range 5–16·6 at.-% Gd showed occurrence a phase transformation at about 1215°C. From X-ray diffraction investigations, it was concluded that this corresponds to an allotropic change Fe17Gd2 from rhombohedral Zn2Th2 type low temperature hexagonal Ni17Th2 high temperature. Both these structures were detected as cast samples Fe–Tb alloys. However, Fe17Tb2 compound, no by differential analysis.MST/1227
A series of Ti based shape memory alloys with composition Ti50Ni48Fe2, Ti50Ni47Fe3 and Ti50Ni45Fe5 were developed by vacuum arc melting under a purified argon atmosphere. The study was designed to evaluate in vivo cytotoxicity the Ti–Ni–Fe alloy system. materials implanted rabbits, blood examination histology various vital organs (liver, heart kidney) performed determine these systems, if any, after 4, 8 12 weeks. results showed that neither cytotoxic nor has any systemic reaction on living...
