Abstract

The invention relates to the technical field of metal matrix composite materials, in particular to a high thermal conductivity particle reinforced aluminum matrix composite material and a preparation method thereof. High thermal conductivity particle reinforced aluminum matrix composite material, including reinforced particles and aluminum alloy, the reinforced particles are evenly distributed in the aluminum alloy matrix, and form a good interface bond with the matrix; the quality of the aluminum alloy and the reinforced particles The ratio is 100: (1-30). The invention optimizes the mass ratio of the aluminum alloy to the reinforcing particles, controls the amount of each component in the aluminum alloy, controls the thermal conductivity of the aluminum alloy and the reinforcing particles, and obtains an aluminum-based composite material with high thermal conductivity and good comprehensive mechanical properties.

Description

technical field

[0001] The invention relates to the technical field of metal matrix composite materials, in particular to a high thermal conductivity particle reinforced aluminum matrix composite material and a preparation method thereof. Background technique

[0002] With the development of electronic communication technology, the product structure is constantly adjusted, the integration level is getting higher and higher, and the power consumption of the product is greatly increased, which brings new challenges to the heat dissipation, volume and weight of electronic communication equipment. Taking 5G wireless base stations as an example, the volume, weight and power consumption are about three times that of 4G products. At the same time, the heat dissipation teeth of the shell are increased in height and density, and light weight is the goal that customers continue to pursue. Particle-reinforced aluminum matrix composites with good die-casting formability and high thermal...
