Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

open access: yesAdvanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

DIRECT FORMATION OF LA(FE,SI)(13) PHASE BY DIRECTIONAL SOLIDIFICATION IN SLOW COOLING RATE

open access: yes, 2014
Direct formation of the La(Fe, Si)(13) phase has been realized by extremely slow cooling in directional solidification technique. A large amount of this magnetocaloric phase of about 85% was found in the as-solidified state.

Evaporative Heat Transfer from an Electrowetted Liquid Ribbon on a Heated Substrate

open access: yes, 2013
Evaporation of narrow water ribbons (of 5 and 7 lL volume) formed on a heated surface is investigated. Chemical and structural patterning of a silicon substrate is employed to fabricate a hydrophilic stripe that bisects hydrophobic pillar arrays of ...

Pyramidal Structures on Yttria‐Stabilized Zirconia after High Temperature Exposure at 1500°C: New Features on an Old Material

open access: yesAdvanced Engineering Materials, EarlyView.
New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...
