“…Therefore we can say that the intrinsic nanohardness values are 1.55, 1.64, 1.61 and 1.36 GPa for AZ63, AZ63-0.1CaO, AZ63-0.3CaO and AZ63-0.5CaO, respectively. Same hardness behavior can be seen in various thin films [18] and magnesium alloys [19].…”

In this study we aimed to produce AZ63 magnesium alloys containing different amounts of CaO, to investigate the nanohardness behaviour of the resulting alloys. These alloys were produced by mechanical alloying under argon atmosphere. Magnesium based alloys with the initial CaO content of 0.1%, 0.3%, and 0.5% were produced by highenergy ball milling, followed by process that involved cold pressing and sintering. These alloys were characterized using scanning electron microscopy, scanning probe microscopy, X-ray diffraction, and nanoindentation methods. Unloading segments of nanoindentation curves were analyzed using Oliver-Pharr method. Experimental results show that measured nanohardness exhibits a peak load dependence. As a result, in these alloys the microstructure and nanohardness depend on the content of CaO.

“…Based on the results of SEM and XRD analysis of BiPbSrCaCuO ceramic superconductors, Karaca et al [14] concluded that the structure of samples has dominant low-T c phase (2212) and c lattice parameter is increasing with increasing Zn content from X-ray diffraction analysis. Moreover, they observed that the grain size of the samples decreases with Zn enrichment in scanning electron microscopy examination.…”

The effect of partial substitution of Ca by Zn in Bi 1.7 Pb 0.3 Sr 2 Ca 2 − x Zn x Cu 3 O y at x = 0.00, 0.05, 0.10, 0.15 and 0.20 levels on the electrical and structural properties was investigated in this work. The characterization of the ceramics prepared by the conventional solid-state reaction method were done by resistance-temperature measurements, XRD, SEM and density analysis. Low levels of Zn substitution of Ca caused significant changes in the properties of the ceramics. The low-T c superconducting properties were enhanced and the fraction of the low-T c (2212) phase were found to increase at x = 0.15 level of Zn substitution at 830°C sintering temperature. Zero resistance was observed only in sample D with x = 0.15 and the T c was determined as 92 K. The SEM micrographs and the density analysis have shown that this was the densest packed ceramic.
