Transformation Volume Effects on Shape Memory Alloys
(MDPI, 2013-07-02)
It is generally accepted that the martensitic transformations (MTs) in the shape memory alloys (SMAs) are mainly characterized by the shear deformation of the crystal lattice that arises in the course of MT, while a ...
Tailoring thermomechanical treatment of Ni-Fe-Ga melt-spun ribbons for elastocaloric applications
(Elsevier, 2019-09)
In the present work, the structural, mechanical and shape memory properties of Ni55Fe16Ga29 (at.%) melt-spun ribbons have been studied with a prospective of application in the elastocaloric devises. Particularly, a special ...
The effect of magneto-crystalline anisotropy on the properties of hard and soft magnetic ferrite nanoparticles
(Beilstein, 2019-07-03)
Recent advances in the field of magnetic materials emphasize that the development of new and useful magnetic nanoparticles (NPs) requires an accurate and fundamental understanding of their collective magnetic behavior. ...
Superelastic behavior of single crystallineNi48Fe20Co5Ga27micro-pillars nearaustenite–martensite critical point
(2021-02-01)
Micro-pillars oriented in austenite along [100], [110], and [111] crystallographic directions were fabricated on the corresponding edges of a single crystalline plate of the Ni48Fe20Co5Ga27 magnetic shape memory alloy ...
Spontaneous Zero-Field Cooling Exchange Bias in Ni–Co–Mn–Sn Metamagnetic Heusler Sputtered Film
(MDPI, 2021-08-26)
Metamagnetic off-stoichiometric Heusler alloys are actively being investigated because of their great potential as magnetocaloric materials. These properties are intimately related to the nanoscale homogeneity of their ...
Neutron Scattering as a Powerful Tool to Investigate Magnetic Shape Memory Alloys: A Review
(MDPI, 2021-05-18)
Magnetic shape memory alloys (MSMAs) are an interesting class of smart materials characterized by undergoing macroscopic deformations upon the application of a pertinent stimulus: temperature, stress and/or external magnetic ...
Temperature Dependent Stress–Strain Behavior and Martensite Stabilization in Magnetic Shape Memory Ni51.1Fe16.4Ga26.3Co6.2 Single Crystal
(MDPI, 2021-06-04)
The superelastic properties and stress-induced martensite (SIM) stabilization have been studied in a shape memory Ni51.1Fe16.4Ga26.3Co6.2 single crystal. The single crystal, characterized by a thermally induced forward ...
Magnetic field-induced rubber-like behavior in Ni-Mn-Ga particles/polymer composite
(Nature Publishing, 2019-03-05)
Single crystalline Ni-Mn-Ga is well known as a prototype ferromagnetic shape memory alloy (FSMA) exhibiting a giant magnetic field-induced strain (MFIS), up to 12%, due to the magnetically driven twin boundary rearrangement. ...
