Embodiment Construction

[0017] see figure 1 , figure 1 It is a flowchart of the steps of the method for improving the compressive plasticity of the amorphous alloy of the present invention.

[0018] In step S102, cutting the amorphous alloy material into a shape with an aspect ratio greater than 0 and less than 1;

[0019] In this step, the aspect ratio refers to the ratio of height to diameter for the amorphous alloy rod, and refers to the ratio of thickness to width for the amorphous alloy plate. Therefore, in this step, for the solid rod of the amorphous alloy, it should be cut into a shape with a height-to-diameter ratio greater than 0 and less than 1; for an amorphous alloy plate, it should be cut into a shape with a thickness-to-width ratio greater than 0 and less than 1.

[0020] Under standard measurement conditions (that is, the ratio of height to diameter is equal to 2.0 to 2.5), when the amorphous alloy material is compressed, the plastic deformation obtained is very small, usually no mo...

Abstract

The invention provides a method and a system for improving the compression plasticity of amorphous alloy. The method for improving the compression plasticity of the amorphous alloy comprises the following steps of: cutting an amorphous alloy material to be in a shape of which the height-diameter ratio is larger than 0 and smaller than 1; and compressing the amorphous alloy material along the height direction so that the plastic distortion of the amorphous alloy material along the height direction reaches 5 percent to 50 percent. The method and the system for improving the compression plasticity of the amorphous alloy can improve the plastic distortion capability of the amorphous alloy material, lead the amorphous alloy material to also have larger compression plasticity at the standard height-diameter ratio, and are simpler to realize without complicated process.

Description

technical field [0001] The invention relates to a method for improving the compressive plasticity of the amorphous alloy, and also relates to a system for improving the compressive plasticity of the amorphous alloy. Background technique [0002] Amorphous alloy is a new type of alloy material with a variety of special and excellent properties developed in the past 10 years. This alloy material is different from traditional low-dimensional amorphous alloy materials such as amorphous strips, films, and micropowders. It has a macroscopic size greater than 1mm. Geometry. Because amorphous alloys have far superior strength, corrosion resistance and other functional properties than crystalline alloys with the same composition, amorphous alloys have significant application prospects. [0003] Amorphous alloys, despite their high strength, have poor ductility in shapes with standard aspect ratios, and known amorphous alloys have a plastic deformation of less than 2% under standard ...
