Abstract

The invention discloses a preparation method for magnetostrictive material and the magnetostrictive material. The preparation method for the magnetostrictive material includes that providing raw material nanometer powder slurry; extruding the slurry, accumulating in linear shape to form a pre-designed three-dimensional model to obtain a sample blank; drying and sintering the sample blank to obtain the cured magnetostrictive material. The preparation method for the magnetostrictive material realizes to manufacture the magnetostrictive material through a three-dimensional mold-less slurry direct-write forming technique, the technique is simple and controlled through program, and different slurry and structure models can be prepared according to needs; the preparation method for the magnetostrictive material manufactures the magnetostrictive material with the complex grid structure in one time, and accordingly the production cost is lowered, the agility is improved, and the magnetostrictive characteristic is greatly improved.

Description

technical field

[0001] The invention relates to the technical field of preparation of magnetic functional materials, in particular to a preparation method of a magnetostrictive material and the magnetostrictive material. Background technique

[0002] Ceramic three-dimensional moldless slurry direct writing molding technology is a moldless direct writing molding method that does not rely on molds and does not require subsequent external processing to prepare micro-scale three-dimensional complex structural functional ceramic materials. This technology uses air pressure as the power to extrude the raw materials, and the designed structure is obtained by controlling the molding equipment layer by layer through the computer program. It is a method integrating computer-aided design, precision machinery and material science. The processing of polymers, functional ceramics and some soft materials (such as paraffin), especially in the preparation of functional ceramic devices, has t...
