Effect of extrusion and introduction of Cu wire on the …
In order to further explore the microstructure difference of AZ31 Mg alloy under extrusion, the EBSD characterization analysis of Mg matrix in as-homogenized, extruded single Mg and Mg/Cu composites was carried out respectively, as shown in Fig. 3.The as-homogenized Mg alloy is mainly composed of coarse grains and small grains(d …
