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, …

Grains in a material are separated by regions called grain boundaries, where there is a misalignment or mismatch in the atomic arrangement between adjacent grains. Grain …

Grain boundary is an interface between the grains generated by a difference in crystal orientation during the sintering process. Fig. 2 shows two types of grain boundaries. The first is a dense …

This chapter discusses the structure and properties of grain boundaries. Interest in the properties and the nature of the junctions between grains in polycrystalline material started with the study …

In this section we discus geometric properties that can be derived from grain boundaries. Lets start by importing some EBSD data and computing grain boundaries. A variable of type …

A grain is a single crystal, within which the atomic lattice and its orientation are contin­ uous. Adjacent grains of the same phase with different orientations are separated by an immaterial …

2009年12月23日 · Understanding how adjacent materials behave at their borders is an essential part of this process. Grain boundaries are the longest-known crystal defects, but although they …

2023年9月1日 · The grain boundary acts as a source for vacancy generation and annihilation, enabling it to function as a diffusion flow and absorption source for maintaining local …

2024年11月5日 · The influence of grain boundary (GB) energy, faceted structure, grain growth, the type of driving force applied, temperature, and other relevant parameters has been …

Engineering the structure of grain boundaries (GBs) by solute segregation is a promising strategy to tailor the properties of polycrystalline materials. Solute segregation triggering phase …
