Hydroxyl‐Terminated Polybutadiene‐Based Molding Powders as an Alternative Route for Manufacturing Pressed Polymer‐Bonded Explosives

Propellants, Explosives, Pyrotechnics, EarlyView.
This study presents an alternative method to manufacture polymer‐bonded explosives by partially curing an HTPB‐based molding powder prior to compaction. The study shows that the length of partial cure time before compaction directly influenced the geometric fidelity, homogeneity, compressive strength, density, and internal microstructure.

Experimental Study on Fine Sediment Infiltration (FSI) Processes in Different Gravel Mixtures

River Research and Applications, EarlyView.
ABSTRACT Fine sediment infiltration (FSI) can lead to riverbed clogging, thereby degrading important habitats for aquatic biota in the hyporheic interstitial zone of gravel‐bed rivers (e.g., by reducing oxygen availability). This stress on rivers may increase from anthropogenic influences and can be counteracted by artificial gravel augmentation to ...

Influence of Heat Treatment and Scan Rotation on the Microstructure of Hot Work Tool Steel Manufactured using Laser Powder Bed Fusion

steel research international, EarlyView.
The study investigates the influence of heat treatment and scan rotation on the microstructure of a modified H13 tool steel manufactured using laser powder bed fusion. Key findings include the refinement of prior austenite grains (PAGs) due to recrystallization and carbide pinning, and the significant impact of scan rotation on the size distribution of

The Clinical Evaluation of Serum WS Biotin, a Novel Encapsulated Form of D‐Biotin With Improved Water Solubility, for Anti‐Hair Shedding Applications. A Prospective Single‐Arm, Nonrandomized, Pretest−Posttest Study

Health Science Reports
Background and Aims Hair shedding is an aesthetic concern increasingly being addressed by the cosmetic industry. Biotin has long been used as an oral supplement to promote hair growth and strength, without solid evidence supporting this practice ...

HWTS 50 Tool Steel Tailored for Laser Powder Bed Fusion: Sliding Wear of Bare Surfaces and Nitriding Response in Comparison with 18Ni300 and AISI H13

steel research international, EarlyView.
This work investigates the wear resistance and nitriding behavior of PBF‐LB/M‐processed Osprey HWTS 50, a lean hot work tool steel. Three heat treatment conditions are compared to conventional wrought H13, H11, and PBF‐LB/M 18Ni300. The study highlights HWTS 50's enhanced nitrogen diffusion, deeper nitriding hardness depth, and comparable or improved ...

In Situ Alloying of H13 Tool Steel With TiC via PBF‐LB/M

steel research international, EarlyView.
H13 tool steel is in situ alloyed with titanium carbides (TiC) in amounts up to 30 wt.%. This approach offers the advantage that the carbides melt only partially during processing, preventing excessive carbon enrichment of the steel matrix. The resulting microstructure consists of coarse, undissolved and fine, reprecipitated carbides, leading to grain ...

Sequential Reduction of Chromite Pellets Using Hydrogen and Silicon Carbide for Carbon Emission Abatement During Ferrochrome Production

steel research international, EarlyView.
H2 prereduction selectively metallizes Fe in UG2 chromite pellets at 1100°C, while silicon carbide becomes active at 1300°C to convert remaining Cr2O3 to carbides and promote Cr metallization. By separating the roles of H2 and SiC, the sequential route reaches up to 65.7% Cr metallization and suppresses in‐furnace CO generation by ≈75% versus ...
