TL;DR: In this article, the authors proposed a criterion to assess whether the fracture of bulk metallic glass (BMG) is essentially brittle or plastic, i.e., if the curvature radius of the crack tip is greater than the critical wavelength of meniscus instability.

TL;DR: In this paper, a theoretical description of thermo-mechanical deformation of metallic glass undergoing one-dimensional simple shearing is presented, which takes into account the momentum balance, the energy balance and the dynamics of free volume.

TL;DR: A quasiperiodic Er oscillation at a frequency of <4 kHz, with a modulation in edge turbulence preceding and following the low-to-high (L-H) confinement mode transition, has been observed for the first time in the EAST tokamak, using two toroidally separated reciprocating probes.

TL;DR: In this article, a new theoretical model was developed to predict the segment spacing, in which the momentum diffusion due to unloading within the shear band had been considered, and the predictions of this model were compared with the experimental and simulated results, which clearly reveal that the proposed model can satisfactorily capture the process of chip segmentation over a wide range of cutting speeds.

TL;DR: In this article, three-point bending experiments were performed on as-cast and annealed samples of Zr52.5Cu17.9Ni14.6Al10Ti5 (Vit105) bulk metallic glasses over a wide range of temperatures varying from room temperature (293 K) to liquid nitrogen temperature (77 K).
