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 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...
متن کاملQuantitative Analysis by X-ray Diffraction
Certain minerals in soil clays may be directly estimated from diffraction line intensity and the mass absorption coefficient of the sample to the radiation used. The main advantages of the method described are that no internal standards or calibration charts are required, and any diffraction line of the component to be estimated may be chosen. The results obtained compare favourably with chemic...
متن کاملX-ray diffraction peak profile analysis of maraged Fe-Ni-Mn steels
X-ray diffraction peak profile analysis was used to identify changes in the lattice distortions during isothermal aging of Fe-10Ni-7Mn (wt. %) maraging steel. Integral peak breadths were analyzed using classical Williamson-Hall equation taking the elastic anisotropy into account. It was found that substantial lattice distortions rise during precipitation hardening which depend strongly on the s...
متن کاملX-Ray Diffraction by NaCl
Abstract: Previous studies have shown that X-rays are produced by electrically accelerating electrons produced by thermionic emission from a hot filament. The emitted electrons are then directed toward a crystal via collimator to study crystal properties. When the target material of the X-ray tube is bombarded with electrons accelerated from the cathode filament, two types of X-ray spectra are ...
