Technical Field
The invention relates to the technical field of material forming, in particular to a preparation method and a system device of a metal-based composite board.
Background
The metal alloy continuous casting and rolling refers to a process of rolling and deforming a metal alloy melt while continuously casting and solidifying. The liquid metal alloy is directly poured into the roll gap, the roll not only plays the role of a crystallizer, but also simultaneously carries out rolling deformation on the metal, and the process is also called liquid rolling or ingot-free rolling. The distance from the front edge of the feeding nozzle to the central line of the casting roll is a casting rolling area, the liquid metal immediately meets the two rotating casting rolls when entering the casting rolling area through the feeding nozzle, the heat of the liquid metal is continuously transferred into the casting rolls from the direction vertical to the casting roll surface, the temperature of the liquid metal attached to the surface of the casting rolls is sharply reduced, and therefore, the liquid metal is cooled, crystallized and solidified on the surface of the casting rolls. With the continuous rotation of the casting roller, the heat of the liquid metal is continuously transferred to the casting roller and is continuously taken away by the cooling water in the casting roller, the crystal continuously grows to the liquid, and the solidified layer is thickened. The liquid metal is contacted with two casting rollers basically at the same time, and crystallized simultaneously, the crystallization process and conditions are the same, the speed and thickness of the formed solidified layer are the same, when the thickness of the solidified layer on two sides is gradually increased along with the rotation of the casting rollers and meets below the central line of the two casting rollers, the casting process is completed, the two casting rollers roll the solidified structure, and the liquid metal is cast and rolled into a cast rolling plate at a certain rolling processing rate, which is the basic principle of continuous casting and rolling.
The particle reinforced metal matrix composite is a metal matrix composite comprising a matrix of a metal or alloy reinforced with particles of carbide, nitride, graphite, or the like. The matrix metal and the reinforcing particles can be selected according to the working condition requirements, the commonly selected particles comprise silicon carbide, titanium carbide, boron carbide, tungsten carbide, aluminum oxide, silicon nitride, titanium boride, boron nitride, graphite and the like, the size of the particles is generally 3.5-10 mu m, the particles with the size of less than 3.5 mu m and about 30 mu m are also selected, and the content range is 5-75 percent according to the needs. The metal matrix includes aluminum, magnesium, titanium, copper, iron, etc. and alloys thereof.

(1) the invention provides a preparation method of a metal-based composite board, which comprises the steps of mixing semi-solid slurry and reinforced particles, carrying out electromagnetic vibration and then carrying out cast rolling to obtain the metal-based composite board with small crystal grains, so that the mechanical property of the metal-based composite board is improved, and the tensile strength and the elongation at break are improved, specifically, in the embodiments 1-9, the grain size is less than or equal to 100.5 mu m, the tensile strength is more than or equal to 168MPa, and the elongation at break is more than or equal to 1.2%, under the preferable condition, the grain size is less than or equal to 50.9 mu m, the tensile strength is more than or equal to 190MPa, and the elongation at break is more than or equal to 2.3%;
(2) it can be seen from the above description that, in the examples 1 and 6 to 9, the mass ratios of the semi-solid slurry and the silicon nitride in the examples 1 and 6 to 7 are controlled to be 15:1, 20:1 and 4:1 respectively, the volume solid ratios of the semi-solid slurry containing the reinforcing phase are respectively 16%, 12% and 30%, and the grain sizes of the metal-based composite sheet materials in the examples 1 and 6 to 7 are respectively 41.2 μm, 45.6 μm and 35.2 μm, the tensile strengths are respectively 220MPa, 204MPa and 246MPa, the fracture elongations are respectively 3.1%, 5.4% and 2.3%, while the grain sizes of the metal-based composite sheet materials in the examples 8 to 9 are respectively 69.2 μm and 50.2m, respectively, compared with the mass ratios of the semi-solid slurry containing the reinforcing phase and the silicon nitride in the examples 8 to 9 are respectively 200:1 and 1.5:1, the tensile strength is 171MPa and 168MPa respectively, and the elongation at break is 2.5 percent and 1.2 percent respectively, so that the invention controls the mass ratio of the semi-solid slurry to the reinforced particle bodies within the range of (20-4): 1, and controls the volume solid phase ratio of the corresponding semi-solid slurry containing the reinforced phase within the range of 12-30 percent, thereby reducing the grain size of the metal matrix composite plate and improving the tensile strength and the elongation at break;
(3) by combining the example 1 and the comparative example 1, it can be seen that, when the temperature of the step (1) in the example 1 is reduced to the semi-solid slurry, compared to the step (1) in the comparative example 1 that the temperature of the step (1) is not reduced to the semi-solid slurry, the grain size of the metal-based composite board in the example 1 is 41.2 μm, the tensile strength is 220MPa, the elongation at break is 3.1%, the grain size of the metal-based composite board in the comparative example 1 is 80.2 μm, the tensile strength is 163MPa, and the elongation at break is 2.8%, and thus, the temperature of the step (1) in the semi-solid slurry can be reduced, and the tensile strength and the elongation at break can be improved;
(4) by combining the example 1 and the comparative example 2, it can be seen that the addition of silicon carbide in the step (2) in the example 1 has a grain size of 41.2 μm and a tensile strength of 220MPa in comparison with the addition of no silicon carbide in the step (2) in the comparative example 2, and the grain size of the metal matrix composite plate in the example 1 is 102.1 μm and the tensile strength is 125MPa in comparison with the addition of silicon carbide in the step (2), and thus, the addition of the reinforcing particles in the step (2) in the present invention can not only meet the requirement of the elongation at break of the metal matrix composite plate, but also reduce the grain size of the metal matrix composite plate and improve the tensile strength;
(5) by combining example 1 with comparative example 3, it can be seen that the grain size of the metal matrix composite plate in example 1 is 41.2 μm, the tensile strength is 220MPa, and the elongation at break is 3.1% compared to the case where the step (3) in comparative example 3 is not performed by performing the electromagnetic vibration, and the grain size of the metal matrix composite plate in comparative example 1 is 76.4 μm, the tensile strength is 162MPa, and the elongation at break is 2.0%.
In summary, according to the preparation method of the metal matrix composite board provided by the invention, after the semi-solid slurry and the reinforced particle bodies are mixed, the metal matrix composite board with small crystal grains is obtained by electromagnetic vibration and cast rolling, so that the mechanical property of the metal matrix composite board is improved, the tensile strength and the fracture elongation are improved, the grain size is less than or equal to 100.5 μm, the tensile strength is greater than or equal to 168MPa, the fracture elongation is greater than or equal to 1.2%, and under the optimal condition, the grain size is less than or equal to 50.9 μm, the tensile strength is greater than or equal to 190MPa, and the fracture elongation is greater than or equal to 2.3%.
