Grain boundaries 意味
WebConsider a second phase of β precipitates out of the matrix, α. It usually occurs at grain boundaries, which act as the nucleation sites facilitating the phase transformation. The potential sites for nucleation include: 1.) Grain facets (two grain junctions - faces) 2.) Grain edges (three grain junction lines) 3.)

In materials science, a grain boundary is the interface between two grains, or crystallites, in a polycrystalline material. Grain boundaries are two-dimensional defects in the crystal structure, and tend to decrease the electrical and thermal conductivity of the material. Most grain boundaries are preferred … See more It is convenient to categorize grain boundaries according to the extent of misorientation between the two grains. Low-angle grain boundaries (LAGB) or subgrain boundaries are those with a misorientation less … See more The energy of a low-angle boundary is dependent on the degree of misorientation between the neighbouring grains up to the transition to high … See more The movement of grain boundaries (HAGB) has implications for recrystallization and grain growth while subgrain boundary (LAGB) movement strongly influences See more Grain boundaries can cause failure mechanically by embrittlement through solute segregation (see Hinkley Point A nuclear power station) … See more A boundary can be described by the orientation of the boundary to the two grains and the 3-D rotation required to bring the grains into coincidence.
