We have studied the effect of the ratio of different rare-earth element on the superconducting properties and phase formation of (Nd0.33Eu0.08Gd0.58)Ba2Cu3Oz ceramic. Bulk NEG samples were prepared using the solid-state reaction process. The superconducting transition for Nd0.33Eu0.08Gd0.58Ba2Cu3Oz is T c ≈90 K and the value of the critical current density (J c) is 13.9 A/cm2 at 77 K under zero magnetic fields. This value is twice as high when compared with the (J c) value of YBCO systems (J c = 7.31 A/cm2). The obtained bulk sample was used for the production of superconducting Ag-sheathed tapes by OPIT method including hot rolling. The critical current density of the obtained tape (337 A/cm2) is one order higher than the one of the bulk sample.

Friction stir welding was applied to join dissimilar aluminum alloys: wrought 2017A and cast AlSi9Mg. The produced weldment was free from cracks and any discontinuities. The weld microstructure was composed of alternating bands of the welded alloys; however, the alloy that was placed on the advancing side (AlSi9Mg) dominated the weld center. The grain size within the particular bands was similar in both alloys. The hardness profile reflected the microstructure formed during welding. The weld microstructure as well as the shape of hardness profile across the weld were justified by numerical simulation of material flow during welding.

We have investigated the influence of Ca-substitution and different rare earths on the microstructure of RE1-x CaxBa2Cu3O7-δ (RE= Y, Eu, Er; x=0, 0.2, 0.3) superconducting ceramics. Scanning electron microscopy, X-ray microanalysis and energy dispersive spectroscopy have been used to study the microstructure and the chemical composition of the samples. A correlation was established between the polycrystalline microstructure and phase formation depending on the additive content. We observed that calcium is distributed uniformly in the crystals. The formation of minor impurity phases improved the sintering conditions.

Textured Ni-YSZ and Co-YSZ (YSZ: cubic yttria stabilized zirconia) cermets prepared by reduction of directionally solidified NiO-YSZ and CoO-YSZ oxide eutectics respectively display a self-organized microstucture formed by âˆ¼400 nm wide alternating lamellae of YSZ and porous metal suitable for electrochemical applications. The electrochemical properties of the cermets depend on their microstructure. We have analyzed the orientation relationships and interfaces both of the oxide composites and cermets using Scanning Electron Microscopy, Transmission Electron Microscopy, X-ray pole figures and Electron Back-Scattering Diffraction. In spite of the similar crystal structure, growth habits and orientation relationships of NiO-YSZ and CoO-YSZ are different. Also the crystallographic behaviour, when cermets are produced, differs. However the metal-YSZ interfaces are about the most stable ones giving good metal-ceramic adhesion. Due to their lamellar microstructure and good metal-ceramic adhesion these composites present long-term stability at working conditions, which makes them good candidates to be used as anodes in solid oxide fuel cells or electrolyzers.

Sintering effects in YBa2Cu3Oz samples with quasi-equal rare earth substitution have been investigated. It has been shown that the Y-123 type compound can be formed when gadolinium is partially substituted (in this case 50% atomic substitution) for yttrium. The superconducting compound was obtained by the optimized ceramic method, including solid-state reaction, melting and sintering, controlled by X-ray diffraction. The microstructure was investigated by SEM and energy dispersive X-ray analyses. An AC susceptibility measurement has shown that T c =93 K. Temperature-dependece of the thermal conductivity (4.5–300 K) of the polycrystalline Y0.5Gd0.5Ba2Cu3O6.94 sample was also measured.

An investigation was carried out to examine the effect of austempering on the microstructure and mechanical properties of nodular cast iron GGG 50 (DIN EN 1563) alloyed with different amount of copper. Optical, scanning electron microscopy and energy dispersive spectroscopy analyses were performed for microstructural characterization. In addition, hardness and tensile tests were carried out for mechanical properties determination. Specimens were austenitized at 900°C for an hour, then austempered for an hour at 330°C in salt bath and cooled at a room temperature in air. The results indicated that the addition of Cu to GGG 50 encouraged pearlite formation in the matrix structure. In addition, with the austempering heat treatment, the structure was transformed from ferrite + pearlite into ausferrite and retain austenite. Furthermore, for the alloy with 2 wt% Cu addition, it was noted that the graphite nodules diverged from sphericity and Cu was concentrated around the graphite. After austempering, mechanical properties were significantly improved and the highest mechanical properties were found at 1.5 wt% Cu.

The microstructure and magnetic properties of nanocomposite hard magnetic Nd-Fe-B-(Re, Ti) materials with different Nd and Fe contents are studied. The role of Re and Ti addition in phase composition and volume fraction of the Nd-Fe-B phase is determined. All samples are annealed at the same temperature of 993 K for 10 min. Mössbauer spectroscopy shows that the addition of 4 at.% of Re to the Nd8Fe78B14 alloy leads to creation of an ineligible amount of the magnetically hard Nd2Fe14B phase. Moreover, the microstructure and magnetic characteristics recorded in a wide range of temperatures for the Nd8Fe79−xB13Mx (x = 4; M = Re or Ti) alloys are also analyzed.
