Microstructure, texture, mechanical properties, and corrosion behavior of biodegradable Zn-0.2Mg alloy processed by multi-directional forging
This study systematically investigated the microstructure, mechanical properties, and corrosion behavior of an extruded Zn-0.2Mg alloy processed by multi-directional forging (MDF) at 100 °C. The mean grain size was remarkably decreased from 17.2¿±¿0.5 µm to 1.9¿±¿0.3 µm, and 84.4% of the microstruct...

This study systematically investigated the microstructure, mechanical properties, and corrosion behavior of an extruded Zn-0.2Mg alloy processed by multi-directional forging (MDF) at 100 °C.

Electron backscattered diffraction examinations revealed that continuous dynamic recrystallization, progressive lattice rotation, and particle-stimulated nucleation mechanisms were recognized as contributing to microstructural evolution. Furthermore, transmission electron microscopy results showed that nanoparticles of Mg/Zn dynamically formed under high strain MDF, while the initial extrusion fiber texture was altered to be¿<¿0001¿>¿parallel to the final forging axis.
