Conical cup properties at room temperature of AZ31 magnesium alloy sheet produced by melt drag process

Abstract

The aim of this study is to clarify formability by conical cup test at room temperature of AZ31 magnesium alloy strip produced by the melt drag process. The strip produced by melt drag process was solution heat treated at 400°C, then was rolled with 5% reduction. We investigated the microstructure, crystal orientation, mechanical properties and formability of the strip using conical cup test at room temperature. Strip produced by melt drag process was compared with commercial rolled sheet. Average crystal grain size of melt drag strip was 39 mm and the crystal orientation was randomized. While melt drag strip had lower proof strength, larger n value and better formability than those one's of commercial sheet.
