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

The diffracted x-rays from a polycrystalline (powder) sample form a series diffraction cones in space since large numbers of crystals oriented randomly in the space are covered by the incident x-ray beam. Each diffraction cone corresponds to the diffraction from the same family of crystalline planes in all the participating grains. When a two-dimensional (2D) detector is used for x-ray powder diffraction, the diffraction cones are intercepted by the 2D detector and the x-ray intensity distribution on the sensing area is converted to an image-like diffraction pattern.

Abstract The pre-synthesized Ni-20Cr nano-crystalline powder was deposited on K21590 boiler steel by cold-spray process. Nano-crystalline Ni-20Cr powder was synthesized by the investigators using ball milling. The nano-structured coating was developed using cold-spray process with an average coating thickness of 200 µm and microhardness of 600 HV having porosity < 1.5%. The high-temperature oxidation behavior of bare and coated samples was studied under cyclic conditions at 900°C for 50 cycles. The kinetics of oxidation was established using weight change measurements for the bare and t

Abstract:
Abstract This study investigates the steam oxidation behavior of Alloy 699 XA, a material containing 30 wt.% chromium and 2 wt.% aluminum that forms protective oxide scales in low-oxygen conditions. The research compares four variants of the alloy: conventional bulk material, a laser powder bed fusion (LPBF) additively manufactured version, and two modified compositions. The modified versions include MAC-UN-699-G, optimized for gamma-prime precipitation, and MAC-ISIN-699, which underwent in-situ internal nitridation during powder atomization. All variants were subjected to steam oxidation test

Abstract:
Abstract Through the application of modern physics concepts, an advanced hydrogen sensor using thermoelectric power (TEP), also known as Seebeck effects, was developed for hydrogen content measurement of face-centered cubic (FCC) alloys, such as UNS N05500. The measured TEP coefficients as a function of hydrogen content developed an anomaly at a specific hydrogen content. Such an indication suggests that phase transformation results with sufficient hydrogen content. The formation of Ni2H phase was found in hydrogen charged UNS N0500 using XRD (X-ray diffraction) and TEM analysis. These results
