Abstract
Analysis of angular dependences of the diffraction peak broadening observed in α-uranium in as-received state, after loading by converging spherical shock wave, low-speed uniaxial deformation, and annealing at 850°С has been presented in this work. Broadening anisotropy identical for all the states investigated has been demonstrated. The authors have attempted to explain the phenomena by Young’s modulus anisotropy of uranium or the crystallite orientation relative to the load applied under plastic deformation.
Highlights
Any deformation leads to broadening of the diffraction peaks in X-ray patterns [1, 2]
This work is focused on an attempt to explain the observed diffraction peak broadening anisotropy in uranium after various effects
The analyzed layer thickness measured in uranium exposed to CuKα radiation was about a micrometer
Summary
Any deformation leads to broadening of the diffraction peaks in X-ray patterns [1, 2]. Dependence of their broadening on the diffraction angle conveys information about the mechanisms and degree of the material deformation. Analysis of the angular dependence in X-ray patterns allowed the authors to reveal a regular nonmonotonicity in the material after various effects. A phenomena like this, in case of -phase Pu-Ga alloy is attributed to Young’s modulus anisotropy and microstresses in the lattice [3]. Young’s modulus anisotropy was taken into account when calculating microstresses in uranium lattice [4]. This work is focused on an attempt to explain the observed diffraction peak broadening anisotropy in uranium after various effects
