Abstract

In this study, a novel type of rotating disc unit was designed and constructed and was used to produce rapidly solidified AA2014 alloy powders. Copper and stainless steel were used as the disc material and the temperature of the cooling water was selected as 0degreesC and 18degreesC. Effects of the production parameters, such as disc material, cooling water temperature, superheat of liquid metal and disc speed on the microstructure and the cooling rate of the powders, have been investigated.
