Grain boundaries 中文
WebIn grain-boundary strengthening, the grain boundaries act as pinning points impeding further dislocation propagation. Since the lattice structure of adjacent grains differs in … WebApr 13, 2024 · Cohesive laws are stress-strain curves used in finite element calculations to describe the debonding of interfaces such as grain boundaries. It would be convenient to describe grain boundary cohesive laws as a function of the parameters needed to describe the grain boundary geometry; two parameters in 2D and 5 parameters in 3D.

WebMar 5, 2024 · Grain boundaries (GBs) modulate the macroscopic properties in polycrystalline materials because they have different atomic and electronic structures from the bulk. Despite the progress on the understanding of GB atomic structures, knowledge of the localized electronic band structures is still lacking. Here, we experimentally … WebIn materials science, grain-boundary strengthening (or Hall–Petch strengthening) is a method of strengthening materials by changing their average crystallite (grain) size. It is based on the observation that grain boundaries are insurmountable borders for dislocations and that the number of dislocations within a grain has an effect on how …

WebThe grain boundary is not flat (not on one plane), but arbitrarily bent. The grain boundary contains (atomic) steps and other local "grain boundary defects". The grain boundary contains foreign atoms or even … WebJul 23, 2024 · Grain boundaries (GBs) are a kind of lattice imperfection widely existing in two-dimensional materials, playing a critical role in materials’ properties and device performance. Related key issues in this area have drawn much attention and are still under intense investigation. These issues include the characterization of GBs at different length …

In thermal equilibrium, each phase (i.e. liquid, solid etc.) of physical matter comes to an end at a transitional point, or spatial interface, called a phase boundary, due to the immiscibility of the matter with the matter on the other side of the boundary. This immiscibility is due to at least one difference between the two ... philippe mouhel facebookWebJun 11, 2024 · Grain boundary is the interface between two grains in a polycrystalline material. Usually, the grain boundary in a polycrystalline material is a 2D defect in the crystal structure. This defect tends to decrease the electrical and thermal conductivity of the material. These grain boundaries are the preferred areas for the onset of corrosion. philippe moucheratWeb晶粒邊界（英語： grain boundary ），簡稱晶界，指多晶材料中晶粒之間的接合區域。 在 結晶學 中晶粒邊界是一種二維的 晶體缺陷 。 晶粒邊界出現在結構相同方向不同的 微晶 區 … philippe nathanWebSep 9, 2024 · The stress relaxation rate increased with the surface area of the grain boundaries in the S V range of 0–4.07 × 10 4 mm −1. This result showed that the grain boundaries had a better effect on promoting dislocation motion near the slip band-grain boundary intersection, rather than inhibiting dislocation motion. philippe muthhttp://www.ichacha.net/grain%20boundary.html philippe nagelmackershttp://cje.ustb.edu.cn/article/doi/10.13374/j.issn2095-9389.2024.01.05.001?pageType=en philippe mutricy bpi
