Abstract Scope |
Quantitative measurements of two-dimensional SAXS intensity at the K absorption edges of Mg and Al have been made for annealed Al-Mg based alloy systems. The SAXS intensity have been normalized by using secondary standard glassy carbon samples calibrated by a primary glassy carbon sample provided by Ilavsky, ANL.The contrast change at the Mg absorption edge agreed with the one expected from the anomalous dispersion of Mg. Thin glassy carbon was found to give well-defined strong scattering at the photon energy of interest. Phase boundary calculated from the normalized SAXS intensity of Al-Mg alloy agreed with the reported ones obtained by other approaches such as calorimetric measurements and thermodynamical assessments. Preliminary results applied to AlMgSi systems will be also shown. |
