Universal Dynamic Scaling for Sub-Yield Aging and Over-Yield Rejuvenation in A Cyclically Driven Metallic Glass
Nannan Ren, Hongfei Zhang, Rui Wan +3
Whether sub-yield aging and over-yield rejuvenation in cyclically deformed amorphous solids share a common physical origin or arise from distinct microscopic mechanisms remains a f…
Mechanical Amorphization of Glass-Forming Systems Induced by Oscillatory Deformation: The Energy Absorption and Efficiency Control
Baoshuang Shang, Xinxin Li, Pengfei Guan +1
The kinetic process of mechanical amorphization plays a central role in tailoring material properties. Therefore, a quantitative understanding of how this process depends on loadin…
Stress-tunable abilities of glass forming and mechanical amorphization
Xinxin Li, Baoshuang Shang, Haibo Ke +4
Mechanical amorphization, a widely observed phenomenon, has been utilized to synthesize novel phases by inducing disorder through external loading, thereby expanding the realm of g…
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…
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…
Atomistic Modelling of Thermal-Cycling Rejuvenation in Metallic Glasses
Baoshuang Shang, Weihua Wang, Alan Lindsay Greer +1
Cycling of a metallic glass between ambient and cryogenic temperatures can induce higher-energy states characteristic of glass formation on faster cooling. This rejuvenation, unexp…
Predicting plasticity in disordered solids from structural indicators
D. Richard, M. Ozawa, S. Patinet +16
Amorphous solids lack long-range order. Therefore identifying structural defects -- akin to dislocations in crystalline solids -- that carry plastic flow in these systems remains a…
Revealing the low-temperature fast relaxation peak in a model metallic glass
B. Wang, L. J. Wang, B. S. Shang +6
By systematically investigating the relaxation behavior of a model metallic glass based on the extensive molecular dynamics (MD) simulations combined with the dynamic mechanical sp…
Elastic avalanches reveal marginal behaviour in amorphous solids
Baoshuang Shang, Pengfei Guan, Jean-Louis Barrat
Mechanical deformation of amorphous solids can be described as consisting of an elastic part in which the stress increases linearly with strain, up to a yield point at which the so…
Local versus global stretched mechanical response in a supercooled liquid near the glass transition
Baoshuang Shang, Jörg Rottler, Pengfei Guan +1
Amorphous materials have a rich relaxation spectrum, which is usually described in terms of a hierarchy of relaxation mechanisms. In this work, we investigate the local dynamic mod…
Role of thermal expansion heterogeneity in the cryogenic rejuvenation of metallic glasses
Baoshuang Shang, Pengfei Guan, Jean-Louis Barrat
Cryogenic rejuvenation in metallic glasses reported in Ketov et al 's experiment (Nature(2015)524,200) has attracted much attention, both in experiments and numerical studies. The…
