A high-resolution synchrotron-based diffraction technique for in situ characterization of deformation behaviour in magnesium alloys

Abstract: To promote accurate lattice-strain measurement and twinning observation during in situ deformation of age-hardenable lightweight magnesium alloys, a high-resolution X-ray diffraction technique was applied using medium-energy synchrotron X-rays ( 21 keV) coupled with a fast Mythen strip detector. This technique allows data collection in transmission geometry, with sufficient grainsampling statistics achieved by rocking the samples during each measurement under step-wise uniaxial tensile/compressive loads.

“…In situ synchrotron diffraction measurements in transmission mode were carried out on the Powder Diffraction beamline at the Australian Synchrotron, using a 21 keV X-ray source (wavelength 0.59041 A ˚) with a beam size of 1.0 Â 0.5 mm along the axial/loading (vertical) and transverse (horizontal) directions, respectively. A detailed description of the in situ experiments undertaken on the beamline is available in the work of Bettles et al (2011) and Wang, Lynch et al (2018). A sample-to-detector distance of 415.261 mm and exposure time for each measurement of 240 s were used.…”

“…For a detailed description of in-situ loading experiments performed on the beamline, the reader is referred to Refs. [40,41]. Diffraction data was acquired using 21 keV beam energy (wavelength 0.59041 Å) and a beam size of 1.0 × 0.5 mm 2 along the axial/loading (vertical) and transverse (horizontal) directions, respectively.…”
