On microstructural constraints for slip transfer in nanotwinned silver

Conference Dates

September 29-October 4, 2019


Micromechanics of bicrystals with selected grain boundary (GB) types is an effective method of understanding dislocation – GB interactions. Micropillar compression tests on bicrystals containing a coherent twin boundary (CTB) [1,2], show that CTBs act as a weak obstacle for slip transfer unlike general high angle grain boundaries. Perfect slip transmission of dislocations through CTBs has been found to be similar to cross slip in fcc metals, and therefore denotes as cross-slip-like slip transfer [2,3].
