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...

EVALUATION OFDISLOCATION STRUCTURE AND CRYSTALLITE SIZE IN WORN AL-SI ALLOY BY X-RAY DIFFRACTION

Abstract: powerful method for the characterization of microstructures of crystalline materials in terms of crystallite size anddislocation structures. In this paper the effect of the sliding on the microstructure of A356 in the as-cast and heattreated conditions are studied, The X-ray phase analysis shows that with increasing applied load, the dislocationdensity is increased, whereas the crysta...

X-ray powder diffraction on proteins

Macromolecular structures are traditionally determined by means of single crystal X ray diffraction from protein crystals of micrometer dimensions. Nevertheless, the growth of good quality single crystals can be very difficult or even impossible, especially in cases of large proteins, membrane proteins or protein complexes. Modern developments of X-ray powder diffraction have allowed the struct...

X-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 ...
