Experimental study of how ‘metallic glass’ forms challenges paradigm in glass research

Unlike in a crystal, the atoms in a metallic glass are not ordered when the liquid solidifies. The properties of these materials are therefore quite different to those of an ordered crystalline material that forms when the same constituents are cooled more slowly. Exactly what is happening at the atomic level during the glass transition process, known as vitrification, is still not completely understood. An team has now gained some crucial insight into this process.
