Influence of defects on the irreversible phase transition in the Fe-Pd doped with Co and Mn [PDF]

, 2018
The appearance of BCT martensite in Fe-Pd-based ferromagnetic shape memory alloys, which develops at lower temperatures than the thermoelastic martensitic transition, deteriorates the shape memory properties.

Non‐Equilibrium Synthesis Methods to Create Metastable and High‐Entropy Nanomaterials

Advanced Science, Volume 13, Issue 11, 23 February 2026.
Synthesis of compositionally‐complex materials is limited by immiscibility of elements. Nonequilibrium synthesis methods reviewed here use ultrafast heating and cooling to overcome this limitation, creating metastable solid solutions and high‐entropy nanomaterials.

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

Rare Metals, Volume 45, Issue 2, February 2026.
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 ...

Magnetic domain structure of epitaxial Ni-Mn-Ga films

, 2012
For the magnetic shape memory effect, knowledge about the interaction between martensitic and magnetic domain structure is essential. In the case of Ni-Mn-Ga bulk material and foils, a staircase-like magnetic domain structure with 90{\deg}- and 180{\deg}-

Relation between the martensite volume fraction and the equivalent transformation strain in shape memory alloys [PDF]

, 2005
International audienceThis study concerns the pseudoelasticity of shape memory alloys. A series of tests under multiaxial loadings and a micro-macro model are used to show the validity of a conjecture concerning the relation between the volume fraction ...

Decoding Cryogenic Deformation Mechanisms in High‐Entropy Alloys: A Comprehensive Review of Microstructural Evolution, Strengthening‐Toughening Synergy, and Serrated Flow Dynamics

cMat, Volume 2, Issue 4, December 2025.
ABSTRACT High‐entropy alloys (HEAs) exhibit exceptional mechanical properties under cryogenic conditions, defying the conventional strength‐ductility trade‐off observed in traditional metal. This review systematically consolidates recent advancements in understanding the deformation mechanisms, microstructural dynamics, and anomalous mechanical ...

Reorientation of Ni–Mn–Ga martensite in rotating magnetic field

, 2010
Reorientation of martensitic variants in the Ni 52.0 Mn 24.4 Ga 23.6 single crystalline disk under magnetic field rotating in the disk plane has been studied. The reorientation proved to be possible in the fields exceeding 130 kAm −1 and started when the
