Near-zero magnetostriction in magnetostrictive FeCo alloys
Scripta Materialia, 2021Abstract Soft magnetic metallic materials are the key components in generators, motors and transformers. The Curie temperatures of currently used soft magnetic metallic materials limit their applications in high-temperature environments.

Grain-oriented (GO) sheet steels are widely used as the core material in large power transformers. The strong magnetostriction in GO sheet steels, however, causes undesirable vibrations and acoustic noises, and is difficult to estimate in the design ...

A new method of magnetostrictivity and magnetostriction measurement
IEEE Transactions on Magnetics, 1989The magnetostrictivity (d) and magnetostriction ( lambda ) of high coupling magnetomechanical amorphous ribbons and wires are determined without the use of a direct magnetomechanical measurement. The method relies on an easily measured magnetic property (permeability) of the magnetostrictive material obtained under the conditions of constant stress and

Abstract Magnetostriction is the phenomenon whereby the shape of a ferromagnetic specimen changes during the process of magnetization. The deformationδl/ldue to magnetostriction is usually very small, in the range 10−5 to 10−6 A deformation of this magnitude can be conveniently measured by means of a strain-gauge technique, the ...

Effective magnetostriction of magnetostrictive composites
Applied Physics Letters, 1998An analytical method is developed for the effective magnetostriction of magnetostrictive composites based on Green’s function technique. For an elastically isotropic composite of magnetostrictive and nonmagnetostrictive phases, the analytical results give explicit effective-medium approximate formulas for the effective magnetostriction that fit well ...

Electro-magnetostriction under large deformation : Modeling with experimental validation
Mechanics of materials (Print), 2019Electro-magneto-elasticity plays a vital role in the advancement of material science. In line with that in the present paper, we model an electro-magnetostriction phenomenon of smart material based on the theory of electro-magneto-elasticity.

Study of Magnetostriction Influence of Electrical Sheet Steel Under Different DC Biases
IEEE transactions on magnetics, 2019Power transformer iron core is mainly composed of electrical sheet steel, which is easily affected by vibration and noise. Therefore, it is necessary to measure the magnetostriction influence of electrical sheet steel. This paper analyzes the performance
