Phenomenological model of anisotropic peak broadening in powder diffraction
Anisotropic line-shape broadening (peak width which is not a smooth function of d-spacing) is frequently observed in powder diffraction patterns, and can be a source of considerable dif®culty for whole-pattern ®tting or Rietveld analysis. A model of the multi-dimensional distribution of lattice metrics within a powder sample is developed, leading naturally to a few parameters which can be varie...
متن کاملAnalysis of asymmetric broadening of X-ray diffraction peak profiles caused by randomly distributed polarized dislocation dipoles and dislocation walls

Republication of this article or its storage in electronic databases or the like is not permitted without prior permission in writing from the IUCr. The problem of asymmetric X-ray diffraction peak broadening caused by dislocations is investigated. The leading term responsible for the ...
متن کاملX-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...
متن کاملDiffraction Line Broadening Analysis if Broadening Is Caused by Both Dislocations and Limited Crystallite Size
The determination of dislocation distribution parameters is discussed for specimens where both strain broadening caused by dislocations and size broadening occur. If the strain broadening is well described by a model due to Wilkens, several methods are possible for the analysis of the broadening of diffraction lines. In sputter deposited nickel layers, three different methods for diffraction li...
متن کاملNeutron Diffraction Experiments
This ISEN award supported research toward improving the energy efficiency of actuators. The focused research objective was to develop next-generation shape memory alloy (SMA) models and structures, to demonstrate this new technology in targeted near-term applications on airplanes. Two research avenues were pursued to enable development of this new technology: 1) neutron diffraction experiments ...
