Abstract

Defects obtained during impact extrusion of EN AW-5754 aluminium alloy during cartridge case production were investigated. In cartridge cases produced from the one metallurgical heat pronounced tendency to earring after impact extrusion observed/appeared. On the other hand, the earring in cartridge cases from the other heat was not observed. Presence of earring is due to the local difference in materials flow during extrusion. This behaviour is attributed to the difference in second phase particle distribution in used preforms (slugs). © 2019, Association of Metallurgical Engineers of Serbia. All rights reserved.
