A metallic glass (MG) annealed above its glass-transition temperature Tg, and cooled, may show an enthalpy increase ΔH, and other property changes. The extent of this thermal rejuvenation depends on the state of the MG (represented by effective cool

We explore the glassy states achievable after a metallic glass is formed on liquid quenching. Samples of La55Al25Ni20 (at.%) metallic glass (rod and ribbon) are studied. The extent of structural relaxation at room temperature is characterized for thi

We use nanoindentation to perform elastic cycling on, and to characterise, the bulk metallic glass Cu46Zr46Al7Gd1. From multiple loading curves, cumulative distributions are determined for several ...

The lack of plasticity in metallic glasses (MGs) is currently the main drawback limiting their commercialization. Mechanical treatments such as high-pressure torsion (HPT) or cold rolling have successfully improved the plasticity of some MGs. We aske

Cryogenic thermal cycling (CTC, between room temperature and 77 K) of a (Cu,Zr)-based bulk metallic glass (MG) leads to substantial reductions in the initial yield load Fy observed on instrumented indentation, and can reverse annealing-induced increa
