All the samples were taken from a centimeter-long, extremely thin ribbon of the metallic glass.
If you took apart the plastic anti-theft tag on a DVD case, you'd find a thin piece of metallic glass that looks like aluminum foil.
Nano-crystallization of metallic glasses is an effective way to prepare nanocrystalline materials.
Scientists recently used a diamond anvil like this one to squeeze tiny samples of metallic glass.
But when scientists squeezed tiny samples of a metallic glass under high pressure, they got a surprise: the atoms lined up in a regular pattern to form a single crystal.
Unlike familiar window glass, metallic glasses are alloys made of metals-in this case cerium and aluminum.
The first samples of this new metallic glass were relatively small glass rods just a millimeter in diameter.
According to Ritchie, "These results mark the first use of a new strategy for metallic glass fabrication and we believe we can use it to make glass that will be even stronger and more tough."
