Probing the local atomic structure of Sr-modified Al–Si alloys
Abstract
Extended X-ray absorption fine structure (EXAFS) spectroscopy and atom probe tomography (APT) measurements were jointly used for the first time to probe the local structure around Sr atoms in Al–10%Sr master alloy and in Al–3%Si–0.04%Sr and Al–12.5%Si–0.04%Sr eutectic alloys in order to study the impact of trace levels of Sr on the morphological changes occurring in Al–Si binary eutectic alloy. EXAFS analysis shows the oxidation states of Sr is …
