Embodiment 1

[0028] Amorphous composite material preparation:

[0029] as attached figure 1 , connect the upper vacuum chamber 2 and the lower vacuum chamber 4, put the master alloy as the matrix into the quartz crucible 9, put the reinforcing phase preform into the mold 17 and place it in the heating furnace 13, start the vacuum unit 19, open the The high vacuum valve I 12 and the high vacuum valve II 14 are evacuated to a high vacuum state; the heating furnace 13 is started to preheat the mold 17 and the reinforcing phase preform; after the heating furnace 13 is heated to 50°C above the melting point of the master alloy and kept for 10 minutes, Start the intermediate frequency induction heating power source 3 to start melting the master alloy, measure and control the temperature of the alloy melt through the infrared thermometer 1, and observe the alloy melting situation through the camera 7. After the alloy is melted, open the inflatable valve I 10 and fill the inert gas into the quar...

Embodiment 2

[0031] Alloy Melting:

[0032]The upper vacuum chamber 2 and the lower vacuum chamber 4 are separated by a blind plate, and the crucible 9 is a water-cooled copper crucible. The pre-configured raw materials are inserted into the crucible 9, the vacuum unit 19 is started, the high vacuum valve 112 is opened, the upper vacuum chamber 2 is pumped to a high vacuum, the intermediate frequency induction heating power supply 3 is started to start smelting, and the infrared thermometer 1 is measured. And the temperature of the alloy melt is controlled, and the situation of the alloy melt can be observed through the camera 7 . After all the raw materials are completely melted, the temperature is kept for 5-10 minutes to make the alloy composition uniform, and then the intermediate frequency induction heating power supply 3 is turned off, and the alloy melting is completed. If the alloy contains volatile components such as Mg, Zn, etc., after the upper vacuum chamber 2 is pumped to a h...

Embodiment 3

[0034] To prepare pure amorphous samples:

[0035] The upper vacuum chamber 2 and the lower vacuum chamber 4 are separated by a blind plate, the crucible 9 is a water-cooled copper crucible, and a copper mold is placed on the blind plate below the crucible. The master alloy Zr 55 Al 10 Ni 5 Cu 30 Put in the crucible 9, start the vacuum unit 19, open the high vacuum valve 112, pump the upper vacuum chamber 2 to high vacuum, start the intermediate frequency induction heating power source 3 to start smelting, measure and control the alloy melt by the infrared thermometer 1. temperature, the melting of the alloy can be observed through the camera 7. After holding the temperature for 2 minutes at a temperature of 150°C above the melting point of the alloy, the inversion device was started, and the alloy was poured into a copper mold to form an amorphous rod. Tumble casting under vacuum avoids the formation of pores in amorphous samples and improves their performance.

A precise temperature control heating furnace is arranged in the lower vacuum cavity; the bottom of the lower vacuum cavity is provided with a quick detachable flange sealing port; and the underside of the outside the lower vacuum cavity is provided with a cooling system. The equipment is mainly used for preparing the non-crystal composite material, can precisely control melting and impregnating temperature of the alloy, and is favorable for obtaining an ideal interface structure and improving performance of the non-crystal composite material. The equipment has multiple functions, and can be also used for melting alloy, preparing pure non-crystal samples, carrying out vacuum heat treatment, and the like.

Description

technical field [0001] The invention relates to melt impregnation and solidification technology, in particular to a multifunctional amorphous composite material preparation equipment. Background technique [0002] Bulk amorphous alloy is a new type of material developed in the early 1990s. It has a series of excellent properties such as high strength, high specific strength, high hardness, high elasticity, high fracture toughness, high corrosion resistance, and high soft magnetic properties. Its mechanical, physical and chemical properties have received close attention in the fields of materials science and engineering, and have broad application prospects in the fields of industry, electronic information, medical and health care, and aerospace. [0003] Bulk amorphous crystals have excellent properties, but their low macroscopic plasticity limits their applications. In order to improve the properties of bulk amorphous, people study the method of preparing amorphous compos...
