Evolution of Microstructures, Texture, Damping and Mechanical Properties of Hot Extruded Mg-Nd-Zn-Zr Alloy

The microstructures, texture, damping and mechanical properties of Mg-Nd-Zn-Zr alloy processed by hot extrusion were investigated in this work. The results showed that the microstructures were markedly refined, and uniformly distributed after hot extrusion. The average grain size was refined to 8.1 ± 1.6 μm (extrusion ratio was 7.65, E1) and 6.28 ± 1.7 μm (extrusion ratio was 12.56, E2), respectively, and the yield strength of the alloy was...
