Local Structural Signatures of Shear Bands in Metallic Glasses via Electron Nanodiffraction
Huyen T. Pham, Daniel East, Chunguang Tang +4
Structural changes in a glass due to deformation are subtle and difficult to quantify using conventional imaging and diffraction techniques. Additionally, transmission electron mic…
Zr-Co-Al bulk metallic glass composites containing B2 ZrCo via rapid quenching and annealing
Yu Chen, Chunguang Tang, Kevin Laws +2
As a promising remedy for overcoming the limited ductility and work softening of bulk metallic glasses (BMGs), BMG composites incorporating a B2 crystalline phase have attracted co…
Natural liquid organic hydrogen carrier with low dehydrogenation energy: A first principles study
Chunguang Tang, Shunxin Fei, G. David Lin +1
Liquid organic hydrogen carriers (LOHCs) represent a promising approach for hydrogen storage due to their favorable properties including stability and compatibility with the existi…
Critical dehydrogenation steps of perhydro-N-ethylcarbazole on Ru(0001) surface
Chunguang Tang, Preetham Permude, Shunxin Fei +3
Understanding of the critical atomistic steps during the dehydrogenation process of liquid organic hydrogen carriers (LOHCs) is important to the design of cost-efficient, high-perf…
Chemical Ordering and Crystal Nucleation at the Liquid Surface: A Comparison of and Alloys
Chunguang Tang, Peter Harrowell
We study the influence of the liquid-vapor surface on the crystallization kinetics of supercooled metal alloys. While a good glass former, , shows no evid…
Temperature rise in shear bands in a simulated metallic glass
Chunguang Tang, Jiaojiao Yi, Wanqiang Xu +1
Temperature rise () associated with shear-banding of metallic glasses is of great importance for their performance. However, experimental measurement of is difficult due t…
Formation and dilatation of shear bands in a Cu-Zr metallic glass: A free volume perspective
Chunguang Tang, Hailong Peng, Yu Chen +1
We study the tensile deformation behaviour of metallic glass CuZr as a function of quenching rate using molecular dynamics simulations. The atomic scale shearing is f…
Atomistic origin of stress overshoots and serrations in a CuZr metallic glass
Chunguang Tang, Kevin Laws, Michael Ferry
In this work we use molecular dynamics simulations to study the stress overshoots of metallic glass CuZr in three scenarios (unloading-reloading, slide-stop-slide, an…
Composition Susceptibility and the Role of One, Two and Three Body Interactions in Glass Forming Alloys: CuZr vs NiAl
Chunguang Tang, Peter Harrowell
In this paper we compare the composition fluctuations and interaction potentials of a good metallic glass former, CuZr, and a poor glass former, NiAl. T…
