Paper Title:
Study of the Microstructure, Texture and Tensile Properties in as-Extruded AZ91 and ZM21 Magnesium Alloys
  Abstract

In this paper, the microstructure, texture and tensile properties of the magnesium alloys AZ91 and ZM21 extruded at 350°C to the ratio 25:1 are investigated. After extrusion, the mean grain size reduces from 400 µm to 30 µm in ZM21 alloy and from 350 µm to 40 µm in AZ91 alloy. Bulk texture analysis indicates the formation of characteristic extrusion texture in both the alloys. The occurrence of dynamic recrystallization, as revealed through necklace structure formation, and the precipitation of second phase (Mg17Al12) particles in the AZ91 alloy are observed.
