摘要

The equilibrium solubility limits of Sc and Zr in Al are only 0.21 at% and 0.08 at% respectively, limiting the maximum achievable strengthening effect of nanoscale Al_3Sc and Al_3Zr precipitates. This solubility limitation can be circumvented through the use of rapid solidification techniques, such as melt spinning, as primary precipitation can be suppressed and a higher degree of initial supersaturation can be achieved. While melt spun ribbons are not immediately useful for structural applications, techniques currently under development may allow for the transfer of such a supersaturation into bulk material. This work discusses the precipitate evolution and strengthening observed in melt spun alloys of Al-0.4at%Sc, Al-0.4at%Zr, and Al-0.4at%Sc-0.4at%Zr over the course of a multistep aging treatment, as observed with X-ray diffraction.
