Rietveld Texture Analysis by Neutron Diffraction of .highly Absorbing Materials
We discuss the impact of strong absorption for thermal neutrons on data analysis and compare absorption corrections in the GSAS and MAUD Rietveld codes for texture and structural parameter refinement. Diffraction data were collected on the neutron powder diffractometer HIPPO at LANSCE from dysprosium and erbium, which are moderate to strong absorbers for thermal neutrons with absorption cross-s...
متن کاملTexture analysis of bronze age axes by neutron diffraction
Neutron diffraction has been utilised as a noninvasive diagnostic tool to gain insight into the ancient metallurgic and manufacturing techniques employed for the production of three bronze age axes from archaic to late bronze age (20th to 13th Century BC). The analysed bronze artefacts are from the “Terramare” and other bronze age settlements near Modena, Italy. Neutron diffraction provides the...
متن کاملEngineering Related Neutron Diffraction Measurements Probing Strains, Texture and Microstructure
Neutron diffraction has been used for engineering applications for nearly three decades. The basis of the technique is powder diffraction following Bragg’s Law. The measured diffraction patterns provide information about internal strains, texture and microstructure, which can be deduced from the peak positions, peak intensities, and peak widths, respectively. Most structural materials are aniso...
متن کاملNeutron diffraction analysis on FINEMET alloys
Neutron diffraction has been used to study in situ the nanocrystallization process of Fe73.5Cu1Nb3Si22.52xBx (x55, 9, and 12! amorphous alloys. Nanocrystallization results in a decrease of both the silicon content and the grain size of the Fe~Si! phase with increasing value of x. By comparing the radial distribution function peak areas with those predicted for ideal bcc and DO3 structure, it ca...
متن کاملStructure determination and Phase Analysis by the use of Neutron diffraction
Neutron diffraction has proven to be an indispensable and highly significant tool since its development 60 years ago. The neutron has unique properties that yield distinct information unavailable otherwise. Chief among these properties is the relative uniformity of the neutron scattering power of atoms across the periodic table, allowing the accurate structure determination of materials compose...
