Embodiment 1

[0026] Amorphous composite material preparation:

[0027] 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 reinforced phase prefabricated body into the mold 17 and place it in the heating furnace 13, start the vacuum unit 19, open High vacuum valve I12 and high vacuum valve II14, evacuate to high vacuum state; start heating furnace 13, preheat mold 17 and reinforced phase preform; The induction heating power supply 3 starts to melt the master alloy, the temperature of the alloy melt is measured and controlled by the infrared thermometer 1 , and the melting of the alloy can be observed by the camera 7 . After the alloy is melted, open the filling valve I10 to fill inert gas into the quartz crucible 9, so that the alloy melt is poured into the mold 17 in the heating furnace 13, then open the filling valve III15, fill in the inert gas to 0.1MPa, and maintain the pressu...

Embodiment 2

[0029] Alloy Melting:

[0030]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. Put the pre-prepared raw materials into the crucible 9, start the vacuum unit 19, open the high vacuum valve I 12, pump the upper vacuum chamber 2 to a high vacuum, start the intermediate frequency induction heating power supply 3 to start melting, and measure it through the infrared thermometer 1 And the temperature of the alloy melt is controlled, and the situation of alloy melting can be observed through the camera 7 . After all the raw materials are completely melted, keep warm for 5-10 minutes to make the composition of the alloy uniform, then turn off the medium frequency induction heating power supply 3, and the alloy melting is completed. If the alloy contains volatile components such as Mg, Zn, etc., after the upper vacuum chamber 2 is evacuated to a high vacuum, the high vacuum valve I 12 can be...

Embodiment 3

[0032] To prepare a pure amorphous sample:

[0033] 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. master alloy Zr 55 Al 10 Ni 5 Cu 30 Put it into the crucible 9, start the vacuum unit 19, open the high vacuum valve I12, pump the upper vacuum chamber 2 to a high vacuum, start the intermediate frequency induction heating power supply 3 to start melting, and measure and control the temperature of the alloy melt through the infrared thermometer 1 , the situation of alloy melting can be observed by camera 7. After keeping the temperature at 150° C. above the melting point of the alloy for 2 minutes, the turning device is started, and the alloy is poured into a copper mold to form an amorphous rod. Inversion casting under vacuum avoids the formation of pores in amorphous samples and improves their performance.

Abstract

The invention relates to a technique for impregnating and solidifying melt, in particular to equipment for preparing a multifunctional non-crystal composite material, and solves the problems of lower macroscopic plasticity of massive non-crystal alloys, limited application range and the like. The equipment is provided with a vacuum chamber consisting of an upper vacuum cavity and a lower vacuum cavity, and the middle of the equipment can be separated by a blind plate and can be also mutually communicated. An inductive heating coil is arranged in the upper vacuum cavity; a melting pot is arranged in the inductive coil; and the outside of the upper vacuum cavity is provided with a camera and an infrared thermometer. 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 composi...
