Abstract

This study investigates the effects of Zn content on the double peak basal textures of extruded Mg-Zn-Al alloys. Two-step plane strain compression (PSC) tests (PSC at room temperature as a first step and PSC at high temperature as a second step) were conducted under various temperatures (200-340 °C) and initial strain rates (0.0002 s-1 and 0.04 s-1) using the extruded ZA11, ZA31 and ZA61 alloys. Additionally, to examine the effects of initial grain size on the double peak basal texture, two-step PSC tests were conducted using annealed ZA61 and cast ZA63 alloys. Tilt angle corresponding to the peak in the double peak basal texture increased with increasing Zn content. This correlation was clearly shown especially at low temperature and high initial strain rate. The tilt angle corresponding to the peak increased with decreasing initial grain size.
