摘要: Abstract Splitting of disclinations (decay into small-power disclinations) at grain boundary junctions in polycrystalline solids is examined theoretically, and related to local amorphization. Energetic characteristics the splitting process are revealed. It shown that such a competes effectively with microcrack generation triple boundaries, causing plastification deformed materials.
