The Initiation of Shear Band Formation in Deformed Metallic Glasses from Soft Localized Domains
Xinyi Wang, Hao Zhang, Jack F. Douglas
It has long been thought that shear band (SB) formation in amorphous solids initiates from relatively 'soft' regions in the material in which large-scale non-affine deformations be…

Fast Dynamics in a Model Metallic Glass-forming Material
Hao Zhang, Xinyi Wang, Hai-Bin Yu +1
We investigate the fast - and Johari-Goldstein (JG) -relaxation processes, along with the elastic scattering response of glass-forming (GF) liquids and the Boson peak, in a s…

Dynamic Heterogeneity, Cooperative Motion, and Johari-Goldstein -Relaxation in a Metallic Glass-Forming Material Exhibiting a Fragile to Strong Transition
Hao Zhang, Xinyi Wang, Hai-Bin Yu +1
We investigate the Johari-Goldstein (JG) -relaxation process in a model metallic glass-forming (GF) material (Al90Sm10), previously studied extensively by both frequency-depende…
