Microstructure and Texture Evolution of Mg-Gd-Y-Zn-Zr Alloy by Compression-Torsion Deformation. [PDF]

Materials (Basel), 2019
Mg–13Gd–4Y–2Zn–0.5Zr alloy was subjected to compression–torsion deformation at 450 °C with a strain rate of 0.001–0.5 s−1 using a Gleeble 3500 torsion unit. The effects of compression–torsion deformation on the microstructure and texture were studied, and the results showed that with the decrease of strain rate, the texture strength decreased, the ...

Microstructure Evolution and Dynamic Recrystallization Behavior of Mg-Gd-Y-Zn-Zr Alloy during Rotating Backward Extrusion. [PDF]

Materials (Basel), 2022
Rotating backward extrusion (RBE) is one of severe plastic deformation (SPD) methods used to produce cylindrical components with a very large strain by a single pass. In this study, the microstructure and texture evolution in the different regions of Mg-12Gd-4Y-2Zn-0.5Zr (wt.%) alloys via RBE process were investigated by using optical microscopy (OM ...

Hot deformation behavior and microstructure evolutions of as-forged Mg-Gd-Y-Zn-Zr alloy

Journal of Materials Research and Technology, 2022
The hot deformation behavior of Mg-9.16Gd-3.03Y-1.44Zn-0.61Zr alloy was examined by hot compression experiments at 623–753 K with strain rates 0.1–20 s−1. Flow stress-strain curves developed an Arrhenius-type equation with adjustment for strain.
