Title: Multiple differential-aperture microscopy.

Abstract

Differential-aperture X-ray microscopy (DAXM) is a powerful approach to 3D tomography with particular relevance to X-ray microdiffraction. With DAXM, scattering from submicron volumes can be resolved. However, the method is intrinsically a scanning technique where every resolved volume element (voxel) requires at least one area-detector readout. Previous applications of DAXM have used a single wire for knife-edge step profiling. Here, we demonstrate a way to accelerate DAXM measurements using multiple wires. A proof-of-principle experiment with a three-wire prototype showed that the speed of measurements can be tripled, but careful calibrations of wires will be required to maintain the spatial accuracy. In addition, related possibilities for accelerating measurements are briefly discussed.

  • Spatially resolved strain distributions in the NiAl matrix and the ~550-nm Mo fibers of a NiAl-Mo eutectic were investigated by micro-beam X-ray diffraction. Position sensitive d-spacings for the individual phases were obtained from Laue patterns. For embedded Mo fibers, the measured elastic strain is consistent with the predicted thermal mismatch strain between the NiAl and Mo phases. However, when the NiAl matrix is etched back to expose Mo micro-pillars, the d-spacing increases to that of unconstrained Mo, indicating release of the compressive residual strain in the Mo fibers.
  • We report the results of Differential Aperture X-ray Microscopy (DAXM) measurements near Te precipitates in CdZnTe grown via low-pressure Bridgman. White-beam Laue patterns were acquired with 3-D spatial resolution (with 0.25 {micro}m resolution in the scanning directions and 1 {micro}m resolution in depth) at depths of up to 35 {micro}m deep normal to the surface. We find very little crystal strain (< 10{sup -3}) or rotation (<0.05 degrees) near Te precipitates. We also examine local deformations in the vicinity of a microhardness indent, and find that although significant rotations exist, the spatial extent is limited to a few tens ofmore » microns. Furthermore, observed crystal strains are limited to 5 x 10{sup -3} or less in regions near the microhardness indent.« less

  • A multistep, non-destructive grain morphology reconstruction methodology that is applicable to near-surface volumes is developed and tested on synthetic grain structures. This approach probes the subsurface crystal orientation using differential aperture X-ray microscopy (DAXM) on a sparse grid across the microstructure volume of interest. Resulting orientation data is clustered according to proximity in physical and orientation space and used as seed points for an initial Voronoi tessellation to (crudely) approximate the grain morphology. Curvature-driven grain boundary relaxation, simulated by means of the Voronoi Implicit Interface Method (VIIM), progressively improves the reconstruction accuracy.
