Description

technical field [0001] The invention relates to the technical field of magnetostrictive materials, in particular to an Fe-Ga-based thin strip alloy material and its energy-saving preparation process and application. Background technique [0002] The magnetostriction concerned by engineering materials mainly refers to the linear magnetostriction, that is, the phenomenon that the material is elongated or shortened in a certain direction driven by an external magnetic field. The magnetostrictive strain is a dimensionless physical quantity, generally represented by × 10 -6 as the unit. [0003] Magnetostriction was discovered by J.P.Joule in 1842, so it is also called the Joule effect. The magnetostriction of ferromagnets generally refers to linear magnetostriction, which is manifested as the linear elongation or shortening of ferromagnets during the magnetization process. Usually the linear magnetostriction coefficient of the material is represented by λ. [0004] Joule dis...
