Additive Manufacturing of Hot‐Work Tool Steel by In Situ Alloying Using Laser Powder Bed Fusion and Directed Energy Deposition—Strategies to Improve Chemical Homogeneity

steel research international, EarlyView.
To support future alloy development a powder mixture is processed by laser additive manufacturing. The powder mixture containing Mo‐ and W‐rich tracers is processed by powder bed fusion using single and double laser exposure and by directed energy deposition which provides drastically enlarged melt pools.

The Influence of the Pretreatment of Tool Steel on the Running‐In Phase of Diamond‐Like Carbon Coatings

steel research international, EarlyView.
The influence of tool steel pretreatment on the running‐in behavior of TiNb‐diamond‐like carbon (DLC) coatings is investigated. Ion etching promotes carbide protrusion and increases coating roughness, while post‐deposition polishing reduces surface asperities.

Historical Development of Zoo Tapir (Tapirus ssp.) Survivorship

Zoo Biology, EarlyView.
The survivorship of tapirs in zoos has improved significantly over historical time. ABSTRACT Tapirs (Tapirus spp.) are large, long‐lived herbivores native to Central and South America and Southeast Asia. All species are currently classified as Vulnerable (T. terrestris) or Endangered (other species) in the IUCN SSC Red List.

Facing Truths About Population Management

Zoo Biology, EarlyView.
Populations of wildlife, and domestic animals have large sinks for surplus animals. By contrast, zoos don't. Humans in industrialized societies are socialized with companion animals, i.e. surplus (i.e., typically denied reproduction) originating from unseen breeding cores.

The effect of Nb and O on the martensitic transformation in Ti–Nb–O alloys

Journal of Applied Crystallography, EarlyView.
Using a newly developed 2D X‐ray diffraction orientation simulation approach to isolate overlapping martensitic reflections, this study demonstrates that niobium controls continuous lattice symmetry evolution, whereas interstitial oxygen induces localized strain fields that nonlinearly govern the structural competition between α″‐martensite and the ...

From mystery to modulation: the structural story of Rb2[Si2O5]

Acta Crystallographica Section B, EarlyView.
The crystal structure of Rb2[Si2O5] has been solved and refined as an incommensurately modulated phase. Each [SiO4] tetrahedron of the phyllosilicate adopts one of two distinct orientations, and the positions of their constituent silicon and oxygen atoms are modeled using a combination of crenel and harmonic positional modulation functions.The crystal ...

The role of absorption in 3D electron diffraction dynamical structure refinement

Acta Crystallographica Section A, EarlyView.
This work establishes the role of absorption in 3D electron diffraction dynamical refinement, where its inclusion is shown to significantly affect refinement outcomes only in high‐Z materials at thicknesses approaching ξg.The role of absorption in 3D electron diffraction is established through analytical theory, simulation and dynamical refinement.
