With no special treatment, aluminum is typically found to have an Al2O3 layer that is 3 nm thick. If spherical aluminum powder prepared with a total diameter of 0.01 mm is used to produce SAP dispersion-strengthened aluminum, calculate the volume percent Al2O3 in the material and the number of oxide particles per cm3. Assume that the oxide breaks into disk-shaped flakes 3 nm thick and 3 × 10-4 mm in diameter. Compare the number of oxide particles per cm3 with the number of solid solution atoms per cm3 when 3 at% of an alloying element is added to aluminum.
