Abstract

The invention relates to a preparation method and preparation mold of an amorphous alloy-copper laminated composite material. The amorphous alloy is an amorphous alloy bar made of 41.25% of Zr, 13.75% of Ti, 12.5% of Cu, 10% of Ni and 22.5% of Be; and the copper is a red copper tube or a brass tube. The outer diameter of the bar is the same with the inner diameter of the copper tube. The preparation method comprises the following steps: under a room-temperature vacuum environment, removing oxide films on the surfaces of the amorphous alloy and the copper through the rubbing effect between the amorphous alloy and the copper; and then heating in vacuum to a temperature in the temperature range of a supercooled liquid region of the amorphous alloy, and keeping the temperature for a period of time to enable the amorphous alloy and the copper to be subjected to atomic diffusion, thus preparing the amorphous alloy-copper laminated composite material. The prepared amorphous alloy-copper laminated material has a tight connection interface between the amorphous alloy and the copper, and the interface is straight and level without any diffusion connection defect such as perforation and the like.

Description

technical field

[0001] The invention belongs to the technical field of composite material preparation, and in particular provides a preparation method of an amorphous alloy-copper layered composite material and a special mold thereof. Background technique

[0002] Due to its special atomic structure of long-range disorder and short-range order, amorphous alloys exhibit more excellent properties than traditional crystalline alloys, such as high strength, high hardness, high corrosion resistance, excellent magnetic properties and certain temperature Superplasticity within the range, etc., has shown great application value in the fields of aerospace devices, precision machinery and information. However, due to the poor room temperature plasticity and small critical size of amorphous alloys, the wide application of amorphous alloys is greatly restricted. Combining amorphous alloys and metals by diffusion bonding can give full play to the complementary advantages of the two on t...
