图3 入射电子束沿<111>和<001>方向的22SiMn2TiB钢扫描透射明场(STEM-BF)像及环形暗场(ADF)像

Fig.3 STEM-BF (a, c) and ADF (b, d) images with the incident beam being parallel to the <111> (a, b) and <001> (c, d) orientations of the 22SiMn2TiB steel (STEM—scanning transmission electron microscopy, BF—bright field, ADF—annular dark-field. Insets show SAED patterns. The region framed with circle in Fig.3a is for obtaining ADF image)
