图10. 合金2道次锻造后同一晶粒内的孪生及扭折现象分析

Fig.10. Analyses of twinned and kinked grains of the alloy in 2-pass
Color online
(a) orientation map of twinned and kinked grains
(b) misorientation angle distribution
(c) orientation coloring map of kink region (Fig.10c hides the twined region of Fig.10a)
(d) in-grain misorientation axes (IGMA) distribution ("pts" is the abbreviation of "points", and means the number of points with the defined misorientation
(e) magnified view of black-lined region in Fig.10a
(f) {0001}, {\mathrm{10}\bar{\mathrm{1}}\mathrm{0}} and {\mathrm{11}\bar{\mathrm{2}}\mathrm{0}} pole figures of grain in Fig.10e (Numbers 1~3 represent the matrix, kinked region and twined region respectively; the arrow in {\mathrm{10}\bar{\mathrm{1}}\mathrm{0}} pole figure means one of the {\mathrm{10}\bar{\mathrm{1}}\mathrm{0}} pole of the kink band and the matrix is coincided; the arrow in {\mathrm{11}\bar{\mathrm{2}}\mathrm{0}} pole figure means one of the {\mathrm{11}\bar{\mathrm{2}}\mathrm{0}} pole of the twin and the matrix is coincided)
