Atomic scale characterization of complex stacking faults and their configurations in cold deformed Fe42Mn38Co10Cr10 high-entropy alloy

Enhancing Oxygen Evolution Reaction Performance: Electrochemical Activation of the Biphasic CoNi/Zn(Fe,Al,Cr)2O4 via Controlled Aluminum Leaching Facilitated Surface Reconstruction

“…[ 43 ] The presence of these nanotwins is closely related to the low stacking layer fault energy of the FCC metallic phase. [ 44 ] An atomic‐scale HAADF‐STEM image of a region in the matrix (marked by a blue arrow in Figure 2b) taken parallel to the [110] zone axis (Figure 2d) and the corresponding FFT pattern (inset in Figure 2d) verify the crystal structure of the matrix is a spinel type Zn(Fe,Al,Cr) 2 O 4 oxide. The atomic planar spacing of the spinel phase was measured to be $${{\mathrm{d}}}_{{\mathrm{11\bar{1}}}}{\mathrm{\ = \ 0}}{\mathrm{.47\ nm}}$$.…”

High Strength and Low Coercivity of Cobalt with Three-Dimensional Nanoscale Stacking Faults

“…All of these cases generated stair-rod dislocations at interaction point (details can be found in Figure S9–10 and Supplementary Note 2). − However, our HRTEM analysis (Figure c) suggests direct intersection of two stacking fault bands without residual dislocations. The major differences may be attributed to fundamental difference between top-down shearing or bottom-up growing strategy, where two incoming partial dislocations will interact following the shear or growth direction, respectively.…”
