Absolute measurements of small-angle X-ray scattering (SAXS) intensities at the K absorption edge of Mg using glassy carbon as an intensity standard were performed. Glassy carbon samples polished for appropriate transmission were prepared as a secondary standard to be used at 1.3 keV. Al-Mg binary alloys were used to assess the metastable phase boundary for the Al3Mg metastable precipitation through the absolute scattering intensity, and the assessed phase boundary agreed with previous reports. Glassy carbon was concluded to be an appropriate candidate for an intensity standard sample for transmission measurements of SAXS in the tender X-ray regions.
Absolute measurements of small-angle X-ray scattering (SAXS) intensities at the K absorption edge of Mg have been performed using glassy carbon as an intensity standard. Glassy carbon samples polished down to give appropriate transmission have been prepared as a secondary standard to be used at 1.3 keV. Al-Mg binary alloys were used to assess the metastable phase boundary for the Al3Mg metastable precipitation from the absolute scattering intensity. The assessed phase boundary agreed with the previous reports. Glassy carbon was concluded to be an appropriate candidate for an intensity standard sample for transmission measurements of SAXS in the tender X-ray regions.
