“…To explore the reasons for the formation of rare-earth texture and anomalous texture, the Schmidt factor (SF) of the characteristic region of each sample is selected for analysis here, as shown in figure 10. Figure 10(a) shows the comparison of the average Schmid factor of each slip system of the three samples, and figure 10(b) shows the schematic diagram of the rotation axis of each slip system [33]. Overall, the DT sample has the most active dislocation activity.…”

In this paper, the Mg-9.32Gd-3.72Y-1.68Zn-0.72Zr (wt%) alloy has undergone three times of repetitive upsetting extrusion deformation. Alloys with different morphologies and distribution patterns of the second phase have been prepared by varying the deformation temperature in each pass. The effects of the second phase on microstructure, texture and mechanical properties are investigated. The results show that (i) the second phase, including Mg5Gd and LPSO phase, has an important effect on the dynamic recrystallization (DRX) behavior of the alloy. (ii) Appropriate lamella distance and block phase size can promote the activation of the slip system and effectively weaken the texture strength. (iii) The DT sample has an effective combination of fine grain strengthening and second phase strengthening due to the reasonable second phase distribution and size, which greatly improves the UTS and YS of the alloy.
