Ultrahigh Strength with Suppressed Flow Instability at Liquid Helium Temperature via Coherent Nanoprecipitation in a Medium‐Entropy Alloy

Advanced Functional Materials, Volume 36, Issue 10, 2 February 2026.
It is demonstrated that severe lattice distortion and coherent nanoprecipitates overcome the strength–ductility dilemma and mitigate discontinuous plastic flow (DPF) at 4.2 K. Such microstructural design enhances both thermal and athermal stress components, leading to exceptional mechanical performance.

A New Family of Ternary Intermetallic Compounds with Dualistic Atomic Ordering – The ZIP Phases

Advanced Materials, Volume 38, Issue 8, 6 February 2026.
The ZIP phases are ternary intermetallic compounds with dualistic atomic ordering, i.e., they exhibit one face‐centered cubic (fcc; space group Fd3¯$\bar 3$m) variant and one hexagonal (space group P63/mmc) variant. The ZIP phases in the Nb‐Si‐Ni system are the Nb3SiNi2 (fcc) and Ni3SiNb2 (hexagonal) ternary IMCs, crystal structure schematics of which ...

Evolution of crystallographic texture and material anisotropy effects resulting from uniaxial deformation for high-strength steels with high manganese content [PDF]

J Appl Crystallogr
The present study investigates the deformation behavior of high‐strength steels and the associated evolution of material anisotropy. Particular focus is placed on the impact of crystallographic texture and intergranular strains on how residual stresses can be evaluated using X‐ray diffraction and the associated assessment of weld seams in the ...

Type II Hot Corrosion of Two Mo‐Si‐Ti Alloys and Mo‐Si‐B With a Salt Deposit of Mixed Na2SO4 and NiSO4

Materials and Corrosion, Volume 77, Issue 2, Page 177-187, February 2026.
Schematic drawings of the hot corrosion mechanisms of (a) Mo‐9Si‐8B (at.%), (b) Mo‐21Si‐34Ti (at.%) and (c) Mo‐20Si‐52.8Ti (at.%) with a NiSO4/Na2SO4 deposit at 700°C in a SO2‐containing atmosphere. ABSTRACT To enhance turbine efficiencies by increasing gas inlet temperatures, new materials must be developed which can withstand harsh corrosive ...

How Mn and Ti Promote Metal Dusting in NiCu Alloys

Materials and Corrosion, Volume 77, Issue 2, Page 166-176, February 2026.
Cu/MnO catalysis mechanisms of CO lead to C uptake in NiCu alloys and a fairly uniform layered metal dusting attack. Mn effectively eliminates the catalytic inhibition benefits of Cu in NiCu alloys. Rather Cu is detrimental if Mn is present as it promotes MnO catalysis.

Metallographic Analysis Of Laser And Mechanically Formed Hsla Steel

, 2010
This research was conducted to develop a correlation between microstructure of HSLA steel and the mechanical properties that occur as a result of both laser and mechanical forming processes of the metal. The technique of forming flat metals by applying laser beams is a relatively new concept in the manufacturing industry.

Influence of Cooling Rates and Titanium Content on Hot Ductility in Niobium‐Fixed Microalloyed Steels

steel research international, Volume 97, Issue 2, Page 719-730, February 2026.
The hot ductility of four microalloyed steels was examined under varying cooling rates and titanium contents. Hot tensile testing and microscopic analysis revealed that ferrite formation and TiNb(CN) precipitation critically influence hot ductility. Lower cooling rates enhance ductility by increasing ferrite thickness and modifying precipitate features,

Alloying Strategies for Secondary Hardening in High‐Boron Cold Work Tool Steels: A Comparative Study

steel research international, Volume 97, Issue 2, Page 731-743, February 2026.
The influence of tungsten, vanadium, manganese, and silicon on the microstructure and tempering behavior of high boron tool steels is investigated. It is shown that tungsten contributes very little, whereas vanadium leads to tempering carbides, detected by atom probe tomography. Manganese and silicon enable solid solution strengthening. A high hardness
