Example Embodiment

[0039] Example 1

[0040] This example is a comparative example.

[0041] The CuAlMn shape memory alloy without any reinforcing phase was prepared by casting process:

[0042] According to the CuAlMn shape memory alloy, Al accounts for 11.9% of the total mass of CuAlMn, Mn accounts for 2.5% of the total mass of CuAlMn, and the rest is the composition of Cu. Pure Cu is placed in a graphite crucible in an intermediate frequency induction heating furnace. After the temperature is raised to the point where Cu is melted, electrolytic Mn and pure Al are added in sequence, and stirred in a counterclockwise direction. Then pour it into a steel mold. After the CuAlMn shape memory alloy is solidified, it is put into the resistance furnace again, and the temperature is raised to 900 ° C. After holding for 10 minutes, it is put into water at room temperature for quenching. CuAlMn shape memory alloy products.

The composite material can better meet application requirements in the technical field of damping, and noise reduction. According to the preparation method of the material, the intrinsic high-damping reinforced-phase multi-layer graphene of a lamellar structure is added into a CuAlMn shape memory alloy by using a vacuum hot rolling technology for the first time, overcoming the defects that in the prior art, the damping improvement degree is limited, the process is complicated; the production period is long, and the like.

Description

technical field [0001] The technical solution of the invention relates to the technical field of composite materials, in particular to an ultra-high damping and high-strength metal matrix composite material and a preparation method thereof. Background technique [0002] With the rapid development of human civilization and modern industrial technology, various mechanical equipment and weapons are becoming more and more high-speed, efficient and automated. However, problems such as vibration, noise and fatigue fracture are becoming more and more prominent. In the industrial field, the vibration of equipment will not only accelerate the fatigue damage of the material or structure of the equipment, but also directly affect the normal use of the electronic devices and actuators of the equipment in severe cases; Due to the structural fatigue caused by vibration, the unavoidable noise generated during the use of submarines will seriously weaken its combat value; in the field of co...
