Information at Sub-Micro and Nano in an Alloy by Small Angle X-ray Scattering and X-ray Diffraction
Journal Title: International Journal of Theoretical and Applied Nanotechnology - Year 2017, Vol 5, Issue
Abstract
The size distribution of sub-micro-sized and nano-sized γ` precipitates, which were electrolytically extracted from AM3 Single Crystal Supper Alloy, was measured by Small Angle X-ray Scattering and other methods. Lack of size evidence from 100nm to 1 μm, many papers are being published with size from 1 nm to 100 nm about nanoparticles, aren’t be regarded as good enough by SAXS in this paper. There may be some nanoparticles between 100nm to 1μm. The measurement results were analyzed statistically and also compared with the same sample measured by SEM and so on, and the difference between discover and quantification of nanoparticles was discussed. TEM, SEM regarded as discover of nanoparticles, and XRD, SAXS regarded as quantification of nanoparticles were discussed. Ordering phase and disordering phase in γ` precipitates were also quantified by Rietveld method and was also completed with TEM. Lack of statistic reliable information from nano-meter to sub-micrometer, TEM and SEM are not good enough for publishing of a paper about size for nanoparticles. After the discussion, conclusions are completed, TEM, SEM for morphology of nanoparticles, SSA for the mean size of nano powder, SAXS and Laser (usually with awful caking data) for size distribution from nano-meter to sub-micrometer. Meanwhile, conclusion of nano structure in nano-particles, two different results from TEM and XRD, discover and quantification, they are fatal to each other, should be published in one paper for the reason not only accurate but also statistics on nano research in future, was done in this paper. Indeed, that means the measurement of atoms in SCSA blade each by each for Feynman’ lecture even that someone could operate atoms each by each is an impossibility mission over the scale of decimeter or millionmeter until now.
