Abstract

The microstructure and phase stability of gas-atomized aluminum alloy powders as a function of the powder particle size in the rapidly solidified condition were studied. With decreasing particle size, the precipitation of intermetallic compounds became suppressed. The precipitate size increased from 10-30 nm to 40-80 nm with an increase in the powder size. Heat treatment of the powders reduced hardness due to particle coarsening and crystallization.
