Abstract

A detailed study of the size, distribution, and morphology of oxide particles in as-sprayed deposited 5083 Al synthesized by reactive atomization and deposition was reported. The results indicated that the oxides exhibit thin-plate morphology and are distributed at prior droplet boundaries, grain boundaries, and grain interiors with a dimensional scale on the order of tenths of micrometers up to a few micrometers. The mechanisms involved in the formation of the observed oxide distribution were analyzed in detail.
