Influence of oscillatory shear on nucleation in metallic glasses: a molecular dynamics study
Baoshuang Shang, Noel Jakse, Pengfei Guan +2
The process of crystal nucleation can be accelerated or retarded by ultrasonic vibration, which is particularly attractive for the addictive manufacture and thermoplastic forming o…
Atomic Origin of Annealing Embrittlement in Metallic Glasses
Rui Su, Shan Zhang, Xuefeng Zhang +3
An atomistic understanding of annealing embrittlement is a longstanding issue for metallic glasses, which is still lacking due to the insurmountable gap between the thermal history…
Cycle deformation enabled controllable mechanical polarity of bulk metallic glasses
Bao-Shuang Shang, Wei-Hua Wang, Peng-Fei Guan
Tuning anisotropy in bulk metallic glasses, ideally isotropic, is of practical interest in optimizing properties and of fundamental interest in understanding the amorphous structur…
Soft mode parameter as an indicator for the activation energy spectra in metallic glass
Shan Zhang, Chaoyi Liu, Yong Yang +2
The activation energy (E_A) spectra of potential energy landscape (PEL) provides a convenient perspective for interpreting complex phenomena in amorphous materials; however, the li…
Atomic nonaffinity as a predictor of plasticity in amorphous solids
Bin Xu, Michael L. Falk, Sylvain Patinet +1
Structural heterogeneity of amorphous solids present difficult challenges that stymie the prediction of plastic events, which are intimately connected to their mechanical behavior.…
Gigahertz Dielectric Polarization of Single-atom Niobium Substituted in Graphitic layers
Xuefeng Zhang, Junjie Guo, Pengfei Guan +2
We have synthesized two Nb@C composites with an order of magnitude difference in the density of single-atom niobium substituted into graphitic layers. The concentration and sites o…
