Dependence of Microstructure and Hardening Behavior on Torsion Strain and Strain Rate in Extruded AZ31 Rods
Source abstract
Abstract
In this study, the effects of torsion strain and strain rate on microstructure and hardening behavior of extruded AZ31 Mg alloy rods are investigated. Torsion deformation can generate abundant extension twins and dislocations and cause the rotation of c‐axis toward extrusion direction. These microstructures exhibit gradient distributions along the radial direction of torsion‐deformed rods. Torsion deformation can effectively enhance the hardness of AZ31 rods. The gradient microstructure leads to a gradient hardness distribution in torsion‐deformed rods. High strain rates can enhance the hardening effect via torsion deformation by promoting increment of dislocation density.
