Compressive deformation behavior of AZ31 magnesium alloy under quasi-static and dynamic loading

Microstructure and mechanical behavior of ECAP processed AZ31B over a wide range of loading rates under compression and tension

“…Also, as the strain rate increased, the twin density increased in all three orientations. Zhao et al (Zhao et al, 2010) studied the compressive properties of cast AZ31 magnesium alloy at different temperatures and strain rates and came to the conclusion that both the strength and ductility increase with increasing strain rate and the peak stress decreases with increasing temperature at a fixed strain rate.…”

Friction phenomena in hydrostatic extrusion of magnesium

“…Since for this temperature the yield stress is approximately constant it is chosen to perform all calculations with the average yield stress value of σ y = 100 MPa. This value is confirmed by the work of Zhao, [40], who also performed compressive deformation measurements of AZ31. He too found a yield stress of around 100 MPa for the strains depicted in Figure 4.10.…”

Microstructural evolution and deformation behaviour of wrought Mg–Al–Zn alloys under dynamic compression

“…2 e , fine and homogeneous grains with a mean grain size of ∼8.5 µm are obtained, which indicates that the DRX takes place fully at 523 K. The ‘prism’ and ‘pyramidal’ slip systems can therefore be activated and the main deformation mechanism changes from twinning to dislocation slip as temperature increases. 22,23 The increase in the DRX frequency can enhance multiplication of dislocations, which can be easily served as nucleation sites. This again indicates that the twinning and pyramidal slip play an important role if the basal slip is inhibited during plastic deformation.…”
