WebApr 13, 2024 · The paper studies the mechanisms of plastic relaxation and mechanical response depending on the concentration of Cu atoms at grain boundaries (GBs) in nanocrystalline aluminum with molecular dynamics simulations. A nonmonotonic dependence of the critical resolved shear stress on the Cu content at GBs is shown. This … WebJun 19, 2024 · Evidence suggests that the interfaces between crystals of the material – the grain boundaries – influence how materials will fail. This area has been the subject of Dr Srikanth Patala’s research. Crystallographies. Dr Patala and his team investigated how crystals come together to form a material and how its structure influences properties ... WebΣ3 grain boundaries form as a result of either growth twinning or deformation twinning in face centered cubic (fcc) metals and play a crucial role in determining the mechanical and electrical properties and microstructural stability. We studied the structure and stability of Σ3 grain boundaries (GBs) in fcc metals by using topological ... short long sleeve t shirts
