Embodiment Construction

[0029] In order to overcome the defects existing in the prior art, the present invention provides a method and device for improving the forming performance of magnesium alloy at room temperature, using the high strain rate deformation method of electromagnetic forming to increase the twin ratio in the magnesium alloy plate, and utilizing two micro-deformations , breaking the microstructure state of the strong basal texture caused by conventional rolling, thereby fundamentally changing the room temperature formability of magnesium alloy sheets. Since the whole process is at room temperature, processes such as homogenization treatment are avoided, and the production efficiency of the magnesium alloy plate is improved.

[0030] Such as figure 1 As shown, the method for improving room temperature formability of magnesium alloys includes the following steps:

[0031] S10: Pretreating the magnesium alloy plate.

[0032] The thickness of the magnesium alloy sheet to be treated is g...

Abstract

The invention provides a method for improving room temperature forming performance of a magnesium alloy. The method comprises steps that B, a magnesium alloy panel is put into a curve mold, and an electromagnetic forming technology is adopted to machine the magnesium alloy panel; and C, the magnesium alloy panel is put into a flat plate mold, and the electromagnetic forming technology is adopted to remachine the magnesium alloy panel, and the flat plate state is recovered. Correspondingly, the invention further provides a device for achieving the method. Above, the electromagnetic forming high-strain-rate deformation method is used for improving the twin crystal proportion inside the magnesium alloy panel, two-time micro deformation is used, the structural state, caused by conventional rolling, of a strong basal texture is broken, and therefore the room temperature forming performance of the magnesium alloy panel is changed fundamentally.

Description

technical field [0001] The invention relates to the technical field of metal processing, in particular to a method and a device for improving the forming performance of a magnesium alloy at room temperature. Background technique [0002] Magnesium alloy has the characteristics of low density, high specific strength, good electromagnetic shielding performance, and outstanding vibration damping performance. It has a very wide application prospect in the fields of electronics, communications, transportation, aerospace and other fields. In recent years, the demand for lightweight and energy-saving materials has further increased the demand for magnesium alloys in the fields of aerospace, automobiles, and 3C products, and put forward higher requirements for their mechanical properties, which cannot be achieved by traditional cast magnesium alloys. Therefore, more and more attention has been paid to magnesium alloy products produced by plastic processing. However, due to the close...
