Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing

Advanced Engineering Materials, EarlyView.
The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Etching of High Purity Zinc [PDF]

, 1963
A method of etching high purity zinc to reveal various etch figures on {101¯0} planes is presented in this paper. Etch figures are formed by polishing in a dichromic acid solution after the introduction of mercury to the crystal surface.

An Assessment of the Impact of Erbium Laser and Conventional Etching Techniques on Microleakage, Shear, and Microtensile Bond Strength of Hydrophobic and Hydrophilic Pit and Fissure Sealant – An In vitro Study

Journal of Indian Association of Public Health Dentistry
Purpose: In recent years, laser etching has emerged as an alternative to conventional acid etching for enamel surface pretreatment due to its drawbacks. This method can be used as a substitute for preparing pits and fissures before sealing.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Copper Nanocrystallization in Anodic Oxide Films of Ti–Cu‐Based Bulk Metallic Glass and Its Effect on the Corrosion Resistance and Cytocompatibility

Advanced Engineering Materials, EarlyView.
Viktoriia Shtefan, Thorgund Nemec, Ute Hempel, Annett Gebert and coworkers demonstrate that anodic treatment of Ti–Cu‐based metallic glass in a nontoxic pyrophosphate electrolyte forms a protective bilayered Ti/Zr‐oxide film enriched with Cu nanocrystals.

Helium isotopic ratios in carbonaceous chondrites: Significant for the early solar nebula and circumstellar diamonds? [PDF]

, 2001
Stepwise etching of acid-resistant residues from carbonaceous chondrites yields a new, extraordinarily low He isotopic ratio for phase Q that might represent early solar nebula composition.

Unusual nanostructures of "lattice matched" InP on AlInAs [PDF]

, 2014
We show that the morphology of the initial monolayers of InP on Al0.48In0.52As grown by metalorganic vapor-phase epitaxy does not follow the expected layer-by-layer growth mode of lattice-matched systems, but instead develops a number of low-dimensional ...

Low-level Laser-assisted Orthodontics in Enamel Etching: An In-vitro Evaluation

Journal of International Clinical Dental Research Organization
Introduction: The use of laser irradiation to etch enamel in preparation for the direct bonding of orthodontic appliances has been studied. This study compares shear bond strength, surface characteristics, and Adhesive Remnant Index (ARI) scores of teeth
