Preparation method of easy-axis texture in magnetic field induced isothermal solidification process

The invention provides a preparation method of an easy-axis texture in a magnetic field induced isothermal solidification process, which comprises the following steps of placing a crystalline material in a vacuum furnace filled with argon, heating the crystalline material to a solidus, heating the solidus to a phase transition temperature formed by a matrix phase, keeping the temperature, applying a static magnetic field, and cooling to the solidus, cutting off a heat source and a static magnetic field, and cooling along with the furnace. In the general solidification process of a large-size crystalline material under the action of a magnetic field, formation of an easy-axis texture of a crystal is very sensitive to the temperature, and when the crystalline material is solidified from the temperature higher than the phase transition temperature formed by a matrix phase, the orientation effect of the magnetic field on the crystal almost disappears; at the moment, the orientation effect of the crystal is simila
