Internal stresses and textures of nanostructured alumina scales growing on polycrystalline Fe(3)Al alloy
(J C P D S-INT CENTRE DIFFRACTION DATA, 2010)
The evolution of internal stresses in oxide scales growing on polycrystalline Fe(3)Al alloy in atmospheric air at 700 degrees C was determined using in situ energy-dispersive synchrotron X-ray diffraction. Ex situ texture ...
Energy dispersive X-ray diffraction spectroscopy for rapid estimation of calcite in copper ores
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
This article presents a novel technique for measuring the concentration of calcite in copper ore samples using energy dispersive X-ray diffraction (ED-XRD). The results are compared with ultraviolet fluorescence spectroscopy ...
Structural and optical characterization of ZnO layers grown by chemical bath deposition activated by means microwaves
(2012-11-27)
ZnO has received increasing attention and been recognized as a promising candidate for applications due to its optoelectronic properties in the UV range. The ZnO is grown by the technique of Chemical Bath Deposition ...
A complex structure in the (beta+gamma(0)) region of the Cu-Al alloys
(Elsevier B.V., 1998-10-23)
The identification, characterization and stability range of the phases present in a series of Cu-Al alloys, with Al content from 11.0 to 15.0 wt.%, were studied by Differential Thermal Analysis (DTA), Optical Microscopy ...
Occurrence and characterisation of calcium oxalate crystals in stems and fruits of Hylocereus costaricensis and Selenicereus megalanthus (Cactaceae: Hylocereeae)
(2016-10)
Detailed description about occurrence of calcium oxalate (CaOx) crystals in the edible vine cactus species Hylocereus costaricensis and Selenicereus megalanthus is scarce. Therefore, we evaluated and characterized the ...
Effect of disturbance induced by the electronic noise on the Energy Dispersive X-ray Diffraction patterns collection
(ELSEVIER, 2009)
The Energy Dispersive X-ray Diffraction (EDXD) proved to be an interesting alternative to its conventional Angular Dispersive counterpart (ADXD) each time the in situ measurements are of concern. Indeed, although its ...
Epitaxial stress and texture in thin oxide layers grown on Fe-Al alloys
(2012-02-01)
The development of internal stress and texture in the oxide scales grown on Fe-15 at.% Al (1 0 0) and (1 1 1) single crystals at 700 °C was determined in situ using synchrotron X-ray diffraction. At this low oxidation ...
