图8 不同变形条件下(图7d中A~E) Mg-10Gd-6Y-1.5Zn-0.5Zr合金变形样品的EBSD像和再结晶体积分数

Fig.8 EBSD images (a-e) and the corresponding dynamic recrystallization (DRX) fractions (f) of Mg-10Gd-6Y-1.5Zn-0.5Zr alloy deformed samples under deformation conditions of 400 oC and 1 s-1 (point A in Fig.7d) (a), 400 oC and 0.1 s-1 (point B in Fig.7d) (b), 400 oC and 0.01 s-1 (point C in Fig.7d) (c), 450 oC and 0.01 s-1 (point D in Fig.7d) (d), and 500 oC and 1 s-1 (point E in Fig.7d) (e) (CD—compression direction, TD—transverse direction, ND—normal direction. Inset in Fig.8f shows the macroscopic morphology of fractured sample at 500 oC and 1 s-1)
