Structure and Properties of Water-Atomized Aluminum Powder Alloy

Abstract

The production of AD33 powder alloy containing extra 1% of iron is examined. The structurization and properties of powders and alloys formed under high-pressure water atomization are analyzed. There is a complex dependence of the particle size and nature of oxide films on the melt temperature, which has be no more than 900 °C. The strength of the powder alloy compacted under different conditions increases by 60–70% as compared with the conventional alloy (without iron) and corresponds to the strength of high-alloy aluminum alloys.
