Tungsten solubility in L12-ordered Al3Er and Al3Zr nanoprecipitates formed by aging in an aluminum matrix

The partitioning behavior of tungsten is studied in two dilute Al-Er-W and Al-Zr-W alloys aged isochronally up to 400 and 475 °C, to form L12-structured Al3Er and Al3Zr nanoprecipitates. Atom-probe tomography reveals low W solubility in the Al3Er and Al3Zr nanoprecipitates (0.071 and 0.234 at.%, res...
