Surface Hardness Measurment and Microstructural Characterisation of Steel by X-Ray Diffraction Profile Analysis
An X-ray diffraction line will broaden considerably when steels change into martensitic structure on quenching. The results presented in this paper show that X-ray diffraction technique can be employed for a rapid and nondestructive measurement of hardness of hardened steel. Measurement on various quenched and tempered steels showed that the breadth of its diffraction peak increased with increa...
متن کاملX-Ray Diffraction and X-Ray Absorption Spectrocopic Analyses for the Ruthenium Perovskites
According to the Rietveld refinements and X-ray absorption studies at the Ru K-edge, it is found that three compounds La2BRuOg (B=Li, Mg, and Zn) are monoclinic with space group of P21/n, and that the mthenium ions with two oxidation states +IV (d4) and +~(d3) are stabilized in an octahedral site of oxide lattices. A correlation is obtained between absorption edge position and the oxidation sta...
متن کاملIntroducing an Optimized Method for Obtaining X-ray Diffraction Patterns of Biological Tissues
Introduction Individual X-Ray diffraction patterns of biological tissues are obtained via interference of coherent scattering with their electrons. Many scientists have distinguished normal and cancerous breast tissue, bone density, and urinary stone types using the X-Ray diffraction patterns resulting from coherent scattering. The goal of this study was to introduce an optimized method for obt...
متن کاملSurface X-ray speckles: coherent surface diffraction from Au(001).
We present coherent speckled x-ray diffraction patterns obtained from a monolayer of surface atoms. We measured both the specular anti-Bragg reflection and the off-specular hexagonal reconstruction peak for the Au(001) surface reconstruction. We observed fluctuations of the speckle patterns even when the integrated intensity appears static. By autocorrelating the speckle patterns, we were able ...
متن کاملSurface analysis of dental amalgams by X-ray photoelectron spectroscopy and X-ray diffraction.
OBJECTIVES It is important to characterize the surface of dental amalgam in order to understand the process of mercury release from amalgam restorations in the oral cavity. The mercury evaporation occurs not only from the newly made restoration but also from the set material. METHODS The surfaces of four different types of amalgams, which had been well set, were analyzed with X-ray photoelect...
