Seeing how grain boundaries transform in a metal

Grain boundaries are one of the most prominent defects in engineering materials separating different crystallites, which determine their strength, corrosion resistance and failure. Typically, these interfaces are regarded ...

Order out of disorder in ice

The glass structure of a material is often believed to mimic its corresponding liquid. Polyamorphism between ices has been used as a guide to elucidate the properties of liquid water. But how many forms of amorphous ices ...

Fluorine flows in, makes material metal

By getting in the way, fluorine atoms help a two-dimensional material transform from a semiconductor to a metal in a way that could be highly useful for electronics and other applications.

Size matters as nanocrystals go through phases

(Phys.org) —Understanding what happens to a material as it undergoes phase transformations – changes from a solid to a liquid to a gas or a plasma – is of fundamental scientific interest and critical for optimizing ...

Tiny but mighty precipitates toughen a structural alloy

Scientists at the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, Knoxville, have found a way to simultaneously increase the strength and ductility of an alloy by introducing tiny precipitates ...
