WebThe grain boundary in polycrystalline materials is not an ideal source and sink of atoms, and a critical driving force is needed if boundaries are to operate as a source. The … WebJun 26, 2024 · Based on the microstructure evolution and n values in the range of 2–3, the dominant deformation mechanism is grain boundary sliding. For the polycrystalline ceramics, when the grains slide over each other, stress concentration will occur at grain boundaries and triple junctions.

WebSep 23, 2024 · A suite of 37 molecular dynamics simulations is conducted at two system sizes to systematically characterize the role of grain boundary (GB) misorientation on spall strength in pure BCC tantalum (Ta). The systems studied consist of bicrystals with a single [110] symmetric tilt grain boundary. Two loading conditions are compared: (i) … WebApr 11, 2024 · Our results show that the spall strength decreases with the decrement of the grain size (i.e., inverse Hall–Petch relationship) when the grain size is larger than 33.5 nm, while grows with a further decrement of the grain size (i.e., Hall–Petch relationship) when the grain size is smaller than 33.5 nm.
