Determination the crystallographic information of hexagonal magnesium via X-ray diffraction profiles

Abstract

Researching the crystallographic information is imperative in hexagonal magnesium. In this paper, the comparative evaluation on the crystallite size and shape, strain and texture are carried with semi-quantitively techniques, such as Williamson-hall function, Halder-Wagner function, March-Dollase function, ellipsoid model and the Rietveld method. Both the Williamson-hall function and Williamson Hall function are suitable to determine the crystallite size and strain, while ellipsoid model is suitable to reveal the crystallite shape. With conformed by the classical texture analysis, the Rietveld method and quantitively texture is suitable to determining the texture with fiber typed texture.
