Electroforming Thin Fe Foils Using ChCl/Urea Deep Eutectic Solvent: Effects of MnCl2 and Current Density on Microstructure and Corrosion Behavior

MetalMat, EarlyView.
This study reports the electroforming of Fe thin foils using ChCl/urea DES. It analyzes the effect of current density and MnCl2 addition in the electroformed samples’ composition and corrosion behavior. It presents new insights into Mn incorporation via Fe₂O₃ doping in the Fe matrix.

Designing High‐Entropy Alloys With Low Stacking Fault Energy Through Interpretable Machine Learning

Materials Genome Engineering Advances, EarlyView.
In this study, we developed an interpretable machine learning (ML) ensemble framework and, by integrating the VEC criterion with the proposed machine learning scoring parameter in the alloy composition screening process, successfully designed multiple CoCrFeNiMn‐based HEAs with TWIP/TRIP effects and without the BCC phase.

Magnetic and martensitic transformations in Ni48Co2Mn35In15 melt-spun ribbons

AIP Advances, 2018
As-solidified Ni48Co2Mn35In15 ribbons were prepared through the melt-spinning method, and their structural, magnetic, magnetocaloric properties, and martensitic transformations were investigated. The inverse martensitic transformation temperature (TA=325

Local atomic arrangement and martensitic transformation in Ni$_{50}$Mn$_{35}$In$_{15}$: An EXAFS Study

, 2007
Heusler alloys that undergo martensitic transformation in ferromagnetic state are of increasing scientific and technological interest. These alloys show large magnetic field induced strains upon martensitic phase change thus making it a potential ...

The Dependence of Properties on Structural Features in Macro/Micro Levels for PBF‐LB Fabricated Porous NiTi Alloy

Rare Metals, EarlyView.
ABSTRACT Porous NiTi alloys are widely used in biomedical and engineering fields. Using the PBF‐LB technique, the TPMS and Voronoi porous parts with a porosity of ∼67% and a minimum feature size of 0.15 ± 0.02 mm were fabricated. Although the bulk sample fabricated with the same parameters is defect‐free, μ‐CT reconstruction on the porous sample ...

Anti-site disorder and improved functionality of Mn$_{2}$Ni{\it X} ({\it X}= Al, Ga, In, Sn) inverse Heusler alloys

, 2014
Recent first-principles calculations have predicted Mn$_{2}$Ni{\it X} ({\it X}=Al, Ga, In, Sn) alloys to be magnetic shape memory alloys. Moreover, experiments on Mn$_{2}$NiGa and Mn$_{2}$NiSn suggest that the alloys deviate from the perfect inverse ...

Twin‐Wire In Situ Additive Manufacturing of NiTiNb Eutectic Alloys: Eliminating Unmelted Nb Particles and Tailored Superelasticity

Rare Metals, EarlyView.
ABSTRACT A major challenge in fabricating eutectic NiTiNb alloys is the incomplete melting of Nb due to its much higher melting point than the NiTi matrix. In this work, a novel electron‐beam freeform additive manufacturing strategy is developed to eliminate unmelted Nb particles and achieve a fully eutectic structure through independent dual‐wire ...

Tweed in Martensites: A Potential New Spin Glass

, 1992
We've been studying the ``tweed'' precursors above the martensitic transition in shape--memory alloys. These characteristic cross--hatched modulations occur for hundreds of degrees above the first--order shape--changing transition.

Dynamic Scenarios of the Formation of Martensite with the {110} Habits in the Ni50Mn50 Alloy [PDF]

, 2019
Martensitic transformation B2–L10 in the ordered alloy Ni50Mn50, which occurs at comparatively high temperatures (980–920 K), is discussed with the use of dynamic concepts of the wave control of the threshold deformation.
