Tension-compression Asymmetry in an Extruded Mg alloy AZ31: Texture and Strain Rate Effects

摘要

The influence of initial texture and strain rate on the mechanical behavior, especially anisotropy and tension-compression asymmetry (TCA) in AZ31 was investigated. The results indicated that the TCA in AZ31 decreased as the strain rate increased, plastic anisotropy increased as the strain rate increased. After compression, the massive twins were observed in AZ31 samples compressed on the extruding direction, while the fraction of twins in samples compressed perpendicular to the ED was smaller.
