Texture 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 کاملRietveld 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 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 کاملCrystal structure of (Li0.5K0.5)2C03 by neutron powder diffraction analysis
The crystal structure of (Li0.5K0.5)2C03 was determined by neutron powder diffraction. A final weighted R-factor of 4.54% was obtained for the refinement of 2373 reflections by the Rietveld method from a sample synthesized using 7Li2CO3 and K2CO3 (99.9% pure). Slight distortion of the CO$units in the monoclinic cell was observed; the O( 1)-C-0(2) angle and CO(3) length are larger than those for...
