Hercynite pinning delivers enhanced creep resistance in Fe₂O₃–reinforced Al6061: experiments and Arrhenius modeling

Abstract Creep degrades lightweight Al alloys as grains coarsen and reinforcing particles coarsen at high temperature. Adding Fe₂O₃ to AA6061 promotes spinel-type (hercynite-like) reaction products et al./Fe₂O₃ interfaces, which Zener-pins grain boundaries and slows coarsening. Uniaxial creep tests...
