Effect of welding position on porosity formation in aluminum alloy welds [PDF]

open access: yes, 1967
Program investigates the effects of varied welding positions on weld qualities. Progressive changes in bead geometry occur as the weld plane angle is varied from upslope to downslope.

An Atomic‐Scale View at γ’‐Fe4N as Hydrogen Barrier Material

open access: yesAdvanced Materials Interfaces, EarlyView.
This study demonstrates the efficacy of γ’‐Fe4N nitride layers, formed via gas nitriding, as hydrogen permeation barriers. Advanced characterization, hydrogen permeation analysis, and DFT calculations reveal a 20 fold reduction in hydrogen diffusion at room temperature.

Reconfigurable Soft Actuators Constructed via Layer‐by‐layer Assembly

open access: yesAdvanced Materials Interfaces, EarlyView.
Stimulated by the energy inputs from heating or humidifying, structural reconfigurations took place in two different materials as manifested by the dynamic structures and mechanical performance, leading to the opportunities of self‐healing and welding. Based on the hierarchical assembly of these two materials with complementary properties, an actuator ...
