Abstract
⺠High energy ball milling process has been successfully employed to produce Al-20Si alloy using scrap Si powders. ⺠Fully finer and homogenous structure could be achieved after 60 min of milling time. ⺠Si particles were not dissolved but uniformly dispersed in the Al matrix in a milled state. ⺠The hardness of as-milled Al-20Si powder increased steadily with the increase of milling time. ⺠Grain size and dispersion strengthening are two mechanisms being responsible for hardness increment.
