Abstract

The invention discloses a rolling device and method for preparing a functionally graded material based on Hall effect. The rolling device is based on a conventional rolling mill, a coil is additionally arranged to generate a magnetic field, electrode plates are additionally arranged on a bearing seat to introduce a pulse current, a binding post is additionally arranged to measure the potential difference between two ends of a metal plate to control the condition of current distributed in a gradient mode, the upper electrode plate is connected to a positive electrode of a power supply, the lower electrode plate is connected to a negative electrode of the power supply, and the pulse current is introduced from the upper electrode plate and back to the negative electrode of the power supply after passing through an upper roller, the metal plate and a lower roller, when the pulse current passes through a plastic deformation zone of the metal plate, the pulse current is distributed in a gradient mode in the plastic deformation zone of the metal plate by the influence of the magnetic field in the broadsiding direction, the properties of the metal plate are further distributed in a gradient mode, so that the functionally graded material is prepared, the current distributed in a gradient mode is controllable, and the properties of the material are further controllable.

Description

technical field [0001] The invention relates to the application field of Hall effect in metal processing, in particular to a rolling device and method for preparing functionally graded materials based on Hall effect. Background technique [0002] Functionally graded materials refer to a class of heterogeneous composite materials whose composition structure and properties change continuously or quasi-continuously in the thickness or length direction of the material, or a new type of functional material whose properties and functions change gradually. It has the following advantages: Compared with multilayer composite materials, there is no obvious interface in functionally graded materials, but the macroscopic properties show gradient changes in space. Compared with traditional materials, functionally graded materials exhibit unique properties that can deal with the problems caused by asymmetric physical parameters. Continuous or gradient changes in material properties provid...
