Grain boundaries are interfaces that separate different crystallographic regions, known as grains, within a polycrystalline material. In nanomaterials, grain boundaries play a crucial role in ...

Using state-of-the-art microscopy and simulation techniques, an international research team systematically observed how iron atoms alter the structure of grain boundaries in titanium. They were in for ...

Grain boundaries are the interfaces between crystallites of differing orientation in a polycrystalline solid and govern a wide range of physical properties. Each boundary is described by five ...
