Enhancing shape recoverable ratio in (Ni50.1Ti34.9Hf15)85Nb15 high-temperature shape memory alloy by thermal-mechanical treatments

Materials Research Letters
The low shape recoverable ratio in NiTiHf high-temperature shape memory alloys was mainly attributed to dislocation generation due to low matrix strength.

Acoustic Emission During Rubber-like Deformation in Ni₅₁Fe₁₈Ga₂₇Co₄ Single Crystalline Shape Memory Alloys

Metals
Acoustic emission, AE, belonging to a rubber-like deformation in a martensitic state after the stabilization aging of the stress-induced martensite (SIM aging) of Ni51Fe18Ga27Co4 single crystals in compression, were investigated.

Overcoming the Damping-Elasticity Paradox via 3D-Printed NiTiSn Nanocomposite. [PDF]

Adv Sci (Weinh)
Here a 3D‐printed nanoeutectic alloy is designed to exhibit a record‐breaking combination of exceptional damping capacity (tanδ > 0.10) and elastic strain exceeding 4.5% at a high stress ≈1500 MPa, overcoming the damping‐elasticity paradox in high damping alloys.

Coexistence and compatibility of martensite reorientation and phase transformation in high-frequency magnetic-field-induced deformation of Ni-Mn-Ga single crystal [PDF]

, 2018
High-frequency magnetic-field-induced Martensite Reorientation (MR) is one of the most important advantages of Ferromagnetic Shape Memory Alloys (FSMAs), but its stability is threatened by dissipation heat accumulation (“self-heating”) of cyclic ...
