Resolving aging dynamics of a 3D colloidal glass
Physical aging is an inherent property of glassy matter, but understanding its microscopic mechanism remains a challenge particularly at the particle level. In this work, we use a confocal microscope to in-situ t...

Unraveling the threshold stress of structural rejuvenation of metallic glasses via thermo-mechanical creep
The competition between physical aging and structural rejuvenation determines the physical and mechanical properties of glassy materials. Thus, the rejuvenation-aging boundary must be identified quantitatively...

How does the initial free volume distribution affect shear band formation in metallic glass?
Introducing heterogeneities into the structure is an effective way to enhance the plasticity in metallic glasses (MGs). As natural heterogeneity, the original randomly distributed free volume in MGs has been f...
