图4 CoCrNiCu MEA/316L不锈钢异种材料的EBSD分析

Fig.4 EBSD analyses of the dissimilar materials of CoCrNiCu MEA and 316L stainless steel (a) bond contrast (BC) image (The high-angle boundaries with misorientation angle >15° and low-angle boundaries with misorientation angle at 2°~15° are marked with black and red lines, respectively) (b) inverse pole figure (IPF) (c) phase distribution (PD) figure (d) kernel average misorientation (KAM) map (e1, e2) comparisons of the IPF (e1) and KAM map (e2) for the local magnification area of dissimilar material interface in Figs.4b and d, respectively (Types 1, 2, and 3 represent the interfaces with complete martensitic transformation, without martensitic transformation, and with incomplete martensitic transformation, respectively)
