Fragility crossover: Mediated by covalent-like electronic interactions in metallic liquids - EurekAlert
In the field of glass and liquid sciences, the so-called fragility is a key concept which characterizes how rapidly the liquid dynamics show down on lowering temperature. However, a long-standing challenge is that the occurrence of crystallization hinders the evaluation of fragility in glass-forming materials. A team of researchers has pushed the boundaries of traditional techniques and successfully gathered crossover data on fragility for various alloy families. They have proposed the underlying origins of fragility in metallic glass (MG) from an electronic structure standpoint and provided insights for material design.
