Abstract: Abstract Isothermal annealing is a very useful strategy in modulating the properties and structures of metallic glasses, which has been regarded as a single relaxation progress. In this work, the enthalpy relaxation of Au-based metallic… read more here.

Abstract: Atomistic simulations reveal that secondary relaxations in metallic glasses originate from string-like atomic motions. The Johari-Goldstein secondary (β) relaxations are an intrinsic feature of supercooled liquids and glasses. They are crucial to many properties of… read more here.
