Figure 6. Deflection behavior of borides. (A) BF-STEM image of M₅B₃ borides sampled from the interface between the matrix and the freckle. Among them, four borides were selected for further study, in which boride 1 is located at the γ/ phase boundary and the others are at the grain boundary. (B) A TKD - phase distribution map, in which borides are marked with black arrows. (C) A TKD - orientation map, in which three-dimensional unit cells of matrix, freckles, and borides are shown to understand their orientation relationship. (D-O) HAADF-STEM, FFT, and high-magnification HAADF-STEM images of the interface between alloys and borides 1-4. (P-S) Schematic diagrams of four borides, respectively.
