Fig. 2: Critical resolved shear stress (CRSS) for different slip modes.
From: Intersectional nanotwinned diamond-the hardest polycrystalline diamond by design
a Calculated CRSS of slip transfer (ST) mode and confined layer slip (CLS) mode. A dislocation pile-up model and principles of virtual work is used for ST and CLS mode, respectively. b Calculated CRSS of confined slip transfer mode I (CST-I), and confined slip transfer mode II (CST-II). For CST-I and CST-II model, it can be considered as a superposition of ST and CLS modes. The inset is schematic of shuffle-set screw perfect dislocation AB, AD, BC and BD reaction with twin boundary TB1 and TB2. GB is grain boundary.
