Abstract A prototype instrument, which provides x-ray powder diffraction and x-ray fluorescence analysis in a compact unit, has been developed to support the needs of NASA for planetary exploration. The instrument uses a 9-watt Fe-anodc x-ray tube and CCD in a fixed geometry for recording powder patterns with a 2θ range of 35°. The fluorescence spectrum for elements below Fe is collected simultaneously with the diffraction data. A shuttered Cd-109 isotopic source with emissions at 22 and 80 keV is used to excite higher energy fluorescence. The low-energy limit for discriminating single photon

Abstract:
Electron induced X-ray mapping together with modern SEM/EDX analysis systems has reached a high level of perfection due to established methods of beam deflection and focusing and today's standard in energy dispersive X-ray detection and data processing. X-ray analysis of specimens based on X-ray excitation (XRF/XRD) is routinely performed on comparatively large specimen areas without conserved spatial information. XRF-/XRD-imaging capabilities are not yet commonly available on standard spectrometers, since both suitable X-ray optical elements are missing and there is a large intensity loss due

Abstract:
Owing to the complex matrix effects, the current approach to quantitative X-ray diffraction (XRD) and X-ray fluorescence (XRF) analyses of mixtures requires calibration lines from standards, and is hence tedious and time consuming. New insights reveal that both the matrix effects and the calibration lines can be eliminated mathematically. Any complex mixture can be transformed into a set of simple binary mixtures. One straightforward formula decodes both XRD and XRF. A single XRD or XRF scan quantifies the chemical compounds or chemical elements in any mixture. The unified and simplified proce

Abstract:
X-ray diffraction (XRD) and X-ray fluorescence (XRF) are widely used analytical techniques for materials characterization; the information they provide can be considered complementary, as the former is mostly used to obtain crystallographic information and analyze phase content, whereas the latter is sensitive to elemental composition. Many researchers and technologists working in a variety of application fields already use them together in some sort of a “combined” approach, by separately performing XRD and XRF data collection and analysis on the same sample and then comparing the analytical

For research and development or for solving technical problems, we often need to know the chemical composition of an unknown mixture, which is coded and stored in the signals of its X-ray fluorescence (XRF) and X-ray diffraction (XRD). X-ray fluorescence gives chemical elements, whereas XRD gives chemical compounds. The major problem in XRF and XRD analyses is the complex matrix effect. The conventional technique to deal with the matrix effect is to construct empirical calibration lines with standards for each element or compound sought, which is tedious and time-consuming.

Abstract:
Abstract The repeated failures of a wear sleeve in a primary refiner processing hardwood chips for bleached chemithermomechanical pulp (BCTMP) high-yield pulp is costly, and required scheduling for maintenance and replacement. Nickel-chromium thermal sprays can be used to protect wear sleeves in this environment because of their resistance to abrasion and aqueous corrosion. The formation of acetic or sulphuric acids within the refining zone was suspected as a corrodant due to naturally occurring acetyl groups during the pulping process, or from decomposition of residual sulphite impregnation l

Abstract:
Abstract The failure investigation of superheater tubes (SA213 Gr T22 grade materials) after 28 years of service at one of the Saudi Basic Industries Corporation (SABIC) affiliates is presented in this paper. The superheater tubes operate within the design conditions at a pressure of 50.8 kg/cm2 (0.722 Ksi) and temperature of 551 °C. The failed tubes exhibit fish-mouth rupture. The microstructure of the superheater tubes was analyzed by optical microscope and scanning electron microscope (SEM) to examine microstructural evolution over the service period. Tube sample composition was determined

Abstract:
Abstract This paper is about a study on the impact(s) of elemental and ionic mercury (Hg) to carbon steel corrosion in sweet and sour environments with and without Corrosion Inhibitor (CI) injection. Evaluation on the effect of mercury (Hg) deposition and the corrosion behaviour via Corrosion Rate (CR) using Linear Polarization Resistance (LPR), solution chemical properties, surface profile and corrosion product analysis are performed. Bubble test was carried out in glass cells and high-pressure rotating cylinder electrode (HPRCE) autoclaves test under multiple variables to study the CR behavi
