Transient x-ray diffraction with simultaneous imaging under high strain-rate loading.

Real time, in situ, multiframe, diffraction, and imaging measurements on bulk samples under high and ultrahigh strain-rate loading are highly desirable for micro- and mesoscale sciences. We present an experimental demonstration of multiframe transient x-ray diffraction (TXD) along with simultaneous imaging under high strain-rate loading at the Advanced Photon Source beamline 32ID. The feasibili...

Simultaneous X-ray diffraction and phase-contrast imaging for investigating material deformation mechanisms during high-rate loading

Using a high-speed camera and an intensified charge-coupled device (ICCD), a simultaneous X-ray imaging and diffraction technique has been developed for studying dynamic material behaviors during high-rate tensile loading. A Kolsky tension bar has been used to pull samples at 1000 s(-1) and 5000 s(-1) strain-rates for super-elastic equiatomic NiTi and 1100-O series aluminium, respectively. By a...

Investigation of material deformation mechanisms during high-rate loading via simultaneous X-ray diffraction and phase contrast imaging

Using polychromatic synchrotron radiation, high-rate X-ray diffraction has been performed in-situ during dynamic tensile loading. Strain rates of 1000/s and 5000/s have been achieved with a miniature tension Kolsky bar for superelastic NiTi and 1100-O series aluminum, respectively. Via altering the ICCD exposure time, single pulse and 22-pulse diffraction has been performed thus resulting in te...

Diffraction enhanced x-ray imaging.

Diffraction enhanced imaging is a new x-ray radiographic imaging modality using monochromatic x-rays from a synchrotron which produces images of thick absorbing objects that are almost completely free of scatter. They show dramatically improved contrast over standard imaging applied to the same phantom. The contrast is based not only on attenuation but also the refraction and diffraction proper...
