Tensile fracture morphologies of bulk metallic glass

RT Qu, M Stoica, J Eckert, ZF Zhang - Journal of Applied Physics, 2010 - pubs.aip.org
The fracture morphology plays a much important role not only for the failure analysis of
materials but also for the clarification of their fracture mechanisms. However, quantitative …

Fractal in fracture of bulk metallic glass

MQ Jiang, JX Meng, JB Gao, XL Wang, T Rouxel… - Intermetallics, 2010 - Elsevier

surface of a typical tough bulk metallic glass, submitted to high-velocity plate impact and …

Nanoscale periodic corrugation to dimple transition due to “beat” in a bulk metallic glass

MQ Jiang, Z Ling, JX Meng, JB Gao, LH Dai - Scripta Materialia, 2010 - Elsevier
We report an intriguing observation that the interaction of brittle nanoscale periodic
corrugations (NPCs) can lead to the formation of ductile dimples on the dynamic fracture …

Energetic criterion on the intrinsic ductility of bulk metallic glasses

YH Liu, K Wang, A Inoue, T Sakurai, MW Chen - Scripta Materialia, 2010 - Elsevier
We report the use of an energetic criterion to assess the deformability of glassy alloys based
on the cooperative shearing model and energy landscape theory. The barrier energy density …
