Most materials, especially metals and ceramics, are crystals. Their atoms are arranged in three-dimensional lattices that ...

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 ...

Researchers developed a method that gradually adds and removes atoms in simulations, enabling realistic modeling of crystal defects that affect material strength.

The orientations of these infinitesimally small separations between individual “grains” of a polycrystalline material have big effects. In a material such as aluminum, these collections of grains ...

A recent NSR paper measures mechanical properties of solids as a function of both crystalline grain size and grain-boundary thickness The world of solid materials is not composed solely of perfectly ...
