Metallic glasses can be softened to different shapes whilst maintaining mechanical properties, and the related thermoplastic processing requires a heating source and an applied force. Here, the authors show an effective thermoplastic approach by a co

BACKGROUND: The bulk metallic glass (BMG), Pd79Ag3.5P6Si9.5Ge2, has a high fracture toughness and has been found to accommodate post-yield stress, unlike most other BMG. Moreover, due to its greater noble gas composition it has a intrinsic corrosion

The lattice vibrational dynamics in ultra-fragile Pt₅₇Cu₂₃P₂₀ and Pt₆₀Cu₂₀P₂₀ glasses were investigated using in situ inelastic neutron scattering to measure the evolution of the phonon density of states (DOS) through the glas

We identify a reduction reaction of boron oxide by Si during melt fluxing of the Fe-Co-Si-B-P system, which results in an unexpected and significant B enrichment and Si depletion in the alloy. Taking this reaction into account, an optimized Fe-Co-Si-

“Designing” metallic glasses to exhibit properties beyond those offered within the narrow composition ranges where glass formation is possible poses a formidable scientific challenge. This challenge may be tackled by forming composite structures

Owing to their glassy nature, metallic glasses demonstrate a toughness that is extremely sensitive to the frozen-in configurational state. This sensitivity gives rise to the so-called “annealing embrittlement”, which is often severe and in many r

Glassy materials exist in nature and play a critical role in technology, but key differences between the glass, liquid and crystalline phases are not well understood. Over several decades there has been controversy about the specific heat absorbed as
