Nanocrystalline elemental powders of Cr, Fe, Ni, and Cu were prepared by high-energy ball milling and studied using EXAFS spectroscopy. Data were acquired in total electron yield to avoid thickness effects, and a detailed analysis was performed to obtain structural parameters. While significant amplitude reduction was observed in the EXAFS signals of the ball-milled powders, reduction in first neighbor coordination number based on curve-fitting was limited to ≤ 15%. The results are consistent… CONTINUE READING
