Initiation and Propagation of Shear Bands in Zr-Based Bulk Metallic Glass Under Quasi-Static and Dynamic Shear Loadings [PDF]
, 2005 The effect of strain rate on the initiation and propagation of shear bands in the Zr41.2Ti13.8Cu12.5Ni10Be22.5 bulk metallic glass under shear loading was investigated. The quasi-static (at a strain rate of 1.5 x 10(-3) s(-1)) and the dynamic shear tests

Mixing‐Driven Defects and Composition Evolution in Multi‐Material Metal Additive Manufacturing
Advanced Science, EarlyView.Operando synchrotron X‐ray imaging coupled with high‐fidelity multiphysics modeling uncovers how inter‐material mixing reshapes keyhole dynamics and drives distinct pore‐formation pathways in multi‐material laser powder bed fusion (LPBF). Composition‐dependent instabilities trigger defects, whereas rescanning suppresses porosity and homogenizes Cu ...

Efficient Adsorption‐Based Direct Air Capture Via Triply Periodic Minimal Surface Architectures
Advanced Science, EarlyView.Architected triply periodic minimal surface (TPMS) contactors reshape direct air capture by replacing straight‐channel diffusion limits with convection‐enhanced CO2 transport. Chaotic advection thins boundary layers and exposes fast adsorption sites, enabling 70%–75% more fast sites, 114% higher productivity, and 51.8% lower energy consumption than ...
