Going super small to get super strong metals

ScienceDaily   -   General News Websites

Metals get stronger as the size of the grains making up the metal get smaller -- up to a point. If the grains are smaller than 10 nanometers in diameter the materials are weaker because, it was thought, they slide past each other like sand sliding...
