Aluminium with a mixed grain size distribution has been prepared using a spark plasma sintering (SPS) technique.To make the samples two kinds of initial powder with 1 nm and 6 nm particle size were mixed in different volume fractions.Several methods for mixing the powders were investigated and it was found that a method combining magnetic stirring and ultrasonic dispersion achieved the most uniform mixing.
