Fig. 1: Schematics of the int-diamond microstructure and its slip modes.
From: Intersectional nanotwinned diamond-the hardest polycrystalline diamond by design
a Structure schematic of int-diamond. Lattices of D1 and D2, D2 and D3, D3 and D4, and D4 and D1 are mirror images across twin boundary TB1, TB2, TB1, and TB2, respectively. GB is grain boundary. b Four dislocation slip modes in int-diamond: slip transfer mode (ST), confined layer slip mode (CLS), confined slip transfer mode I (CST-I), and confined slip transfer mode II (CST-II). c Schematic of shuffle-set screw perfect dislocation BD and AD reaction with TB when it reaches TB. d The stress-dependent activation energy of shuffle-set screw perfect dislocation BD and AD reaction with TB.
