Uniaxial and Plane Strain Compression Behaviour of Magnesium Alloy AZ31: A Comparative Study


Article Preview

Texture evolution and microstructure development of hot extruded magnesium alloy AZ31 deformed by PSC and uniaxial deformation at select temperatures and a constant strain rate of 10-4 s-1 were investigated and compared using X-ray techniques, electron back scattered diffraction (EBSD) and optical microscopy. At a deformation temperature of 200 °C both deformation routes resulted in a similar crystallographic texture and showed a heterogeneous microstructure consisting of highly deformed zones appearing as huge and/or elongated grains containing twins and shear bands embedded in a very fine-grained microstructure. High temperature deformation (400 °C) gave rise to completely different deformation textures for the two processes. Uniaxial deformation tended to randomize the initial extrusion texture, whereas in PSC a prismtexture {10-10}<11-20> prevailed. The flow stress was found to be strongly dependent on loading conditions and deformation modes.
