X-ray Diffraction Analysis

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...

X-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...

X-Ray Diffraction Analysis of GaN/InGaN

Quantitative 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...

X-ray diffraction.

where the peak shapes were described by a pseudo-Voigt function and the background was modeled with an 6-term polynomial. Additionally, the PXRD patterns obtained at room temperature and 100 K were analyzed by Le Bail refinement using the GSAS and EXPGUI software, 2,3 where the peak shapes were described by a pseudo-Voigt function (CW profile function 3) and the background was modeled with an 4...
