Shear stress induced lattice distortion and incoherence at the nanotwinned region. (a,c) High-resolution HAADF-STEM images demonstrating parallel multi-nanotwin TBs along the (\(11\overline{1}\)) plane are indicated by the dashed lines and (b,d) corresponding GPA strain maps showing the shear strain (strain tensor component εxy) of the (a,b) as induction thermal plasma processed and (c,d) nitrided FeNi NPs. The colour scale bar for strain ranges from − 10% (dark blue) to + 10% (white).
