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

Advanced 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 ...

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

Advanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Investigating the factors influencing RDX shock sensitivity [PDF]

, 2012
The shock sensitivity of RDX (cyclotrimethylenetrinitramine) is dependent upon factors including crystal size, morphology, internal defects, surface defects and HMX content.

Effects of Dipentaerythritol and Cellulose as Additives on the Morphology of Pentaerythritol Crystals

Crystals
The crystal habit of pentaerythritol (PE) crystals is usually rod-shaped, which may lead to low bulk density and bad flowability compared with low aspect ratio crystals.

Preparation of Enzyme Crystals with Tunable Morphology in Membrane Crystallizers

Industrial & Engineering Chemistry Research, 2005
Trypsins were crystallized by using membrane crystallization techniques, both in static and dynamic configurations. Crystal size distribution analysis revealed the high uniformity in size of the products that is achievable. Crystals produced by using membrane crystallization methods are more uniform than those obtained in conventional batch experiments.

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

Advanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

The self-seeded growth of InAsSb nanowires on silicon by metal-organic vapor phase epitaxy [PDF]

, 2014
We present a study on the growth of InAs1-xSbx alloy nanowires directly on Si (111) substrates via a self seeded mechanism for the first time. Through varying group V flow rate ratios, InAs1-xSbx nanowires with x = from 0 to 0.43 are obtained.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Crystal growth of CO2 hydrate formed in the system of CO2 + water + trehalose toward the development of solid carbonated foods

International Journal of Food Properties
Application of CO2 clathrate hydrate as a constituent of solid carbonated foods is an emerging new idea to utilize the large gas-storage capacity of this material.
