MODELING PROCESSES IN ACCOMMODATIVE TRIPLE JUNCTION NANOCRYSTALS WITH DIFFERENT SIZES GRAIN
The direct model experiments and molecular dynamics investigated the development of accommodative processes in triple junctions (TJ) tricrystals and nanocrystals with different grain sizes in the high-temperature creep. Dislocation nucleation is shown «fold», self-organization of adjacent triple junctions in the form of cooperative «propeller» migration of grain boundaries (GBs) and the rotation of nanograins.
