Abbreviated Series Title Binary aluminum alloys with 0.03-0.06 at.% RE (RE = Yb or Er) were aged to produce coherent, nanosize Al3RE precipitates in an α-Al matrix. The temporal evolution of precipitate radii and matrix concentrations at 300 °C are measured by transmission electron microscopy and localelectrode atom-probe tomography, respectively. The temporal dependence of the matrix concentration of each RE is utilized to determine its solubility in Al. The solubility as well as the coarsening rate constants are used to determine the diffusivity of each RE in α-Al and the α-Al/Al3RE interfacial free energies at 300 °C. When compared to Sc, both Yb and Er exhibit smaller solubilities but larger diffusivities in α-Al and larger α-Al/Al3RE interfacial energies.
