The formation of nano-dimensional metallic Al precipitates in alumina due to the reduction of the host matrix as a result of ambient temperature ion implantation of Y ions is examined. The formation and growth of Al precipitates are dependent on both the Y ion dose and the energy available to the matrix, as reported here. Reducing the ion dose from 5 × 1016 to 2.5 × 1016 ions/cm2 results in smaller precipitates; 10.7 ± 1.8 nm to 9.0 nm ± 1.2 nm, respectively, for incident ion energies of 150… Expand
