Model for strain and magnetization in magnetic shape-memory alloys

Journal of Applied Physics, 1998
The large magnetic-field-induced strains observed in martensitic phases based on Ni2MnGa and in other magnetic shape memory alloys are believed to arise from a process of twin-boundary motion rather than magnetostriction. The dependence of strain on magnetization, e(M), generally shows a large component that is linear (rather than quadratic) in M below

Shape memory and magnetic properties of Co–Al ferromagnetic shape memory alloys

Materials Science and Engineering: A, 2006
Abstract Martensitic transformation from the face-centered cubic to the hexagonal close-packed structure, shape memory (SM) effect and magnetic properties in the Co–14 at.% Al alloy were investigated and the microstructures of the martensite were examined using transmission electron microscopy.

Magnetic-field-induced changes in magnetic shape memory alloys

Materials Science and Engineering: A, 2008
Abstract First-principles calculations have been used to investigate the physical properties of magnetic shape memory alloys. We find that the martensitic instability of the high-temperature cubic phase in X2YZ ( X = Fe , Co, Ni, Pd; Y = Mn , Fe, Co; Z = Al , Ga, Ge, In, Sn) is strongly influenced by the anomalous change of the ...

Use of Magnetic Induction to Activate a "Touchless" Shape Memory Alloy Implantable Penile Prosthesis.

Journal of Sexual Medicine, 2019
INTRODUCTION We describe a novel physiologic penile prosthesis that uses shape memory alloy properties to mimic the transition between a flaccid and erect penis using magnetic induction instead of hydraulic pressure.

Additive manufacturing of magnetic shape memory alloys

Ni–Mn–Ga-based magnetic shape-memory alloys (MSMAs) are renowned for their large magnetic field–induced strains, making them attractive for compact magnetically controlled actuators requiring high response frequencies and large reversible deformations. This chapter aims to provide a structured framework for exploring the additive manufacturing (AM) of ...

Magnetic and mechanical properties of FeNiCoTi magnetic shape memory alloy

Sensors and Actuators A: Physical, 2000
FeNiCoTi is a promising candidate to show the magnetic shape memory (MSM) effect in an alloy with a high saturation magnetization and low cost. Material properties in this alloy can be controlled through both composition and heat treatment, and the effects of both have been studied.

Magnetic properties of Mn₂NiSn shape memory alloy

Journal of Physics: Condensed Matter, 2013
In this paper, we present the magnetic properties of the inverse Heusler Mn2NiSn alloy computed by ab initio density functional theory (DFT) calculations in order to understand the large magnetic moments observed in experiments in contrast to smaller values obtained in previous ab initio calculations.

Tailored Magnetic Springs for Shape-Memory Alloy Actuated Mechanisms in Miniature Robots

IEEE Transactions on robotics, 2019
Animals can incorporate large numbers of actuators because of the characteristics of muscles; whereas, robots cannot, as typical motors tend to be large, heavy, and inefficient.
