X-ray fluorescence holography was applied to dilute Mg99.2Zn0.2Y0.6 alloy annealed at 520°C for 5 h obtain atomic images around Zn atom. In spite of the extremely low concentration solute-element, clear hologram patterns were obtained. The reconstructed revealed that atom in this mainly occupy hcp Mg site. This finding is consistent with transmission electron microscope image, where fcc-type st...

Dilute Al–Er-Sc-Zr-Si alloys strengthened by coherent Al3(Er,Sc,Zr)(L12) nanoprecipitates have excellent coarsening- and creep-resistance up to 400 °C. Herein, the effects of micro-additions 0.25 at.% Mn and/or 0.10 Mo a dilute Al-0.08Zr-0.014Sc-0.008Er-0.09Si (at.%) alloy are investigated with respect precipitate evolution resulting strengths after different aging treatments. Both provide soli...

Microstructural length scales, such as dendritic spacings in cast metallic alloys, play an essential role the properties of structural components. Therefore, quantitative prediction scales through simulations is important to design novel alloys and optimize processing conditions integrated computational materials engineering (ICME). Thus far, comparisons between experiments primary dendrite arm...

The internal oxidation o f dilute Pd alloys has been studied by XAS. Pt, Au, Pb and Bi in Pd form no impurity-oxygen complexes. Y, Nb, Gd, Yb, Lu, H f , Th, Zr and Mo precipitate at 1050°C as oxides. In a recent paper /1/ it was shown how X-ray absorption spectroscopy (XAS) can be used to investigate the internal oxidation of impurities in dilute alloys. It was demonstrated in the case of a @Zr...
