Problems solved by technology

However, these particles have many disadvantages as reinforcements. For example, adverse interfacial reactions will occur at the interface between the matrix and the reinforcement, which will cause peeling problems at the interface, and will cause a decline in the density and mechanical properties of the composite material.

Abstract

The invention discloses an amorphous alloy reinforced aluminum matrix composite and a preparation method thereof. The composite takes an aluminum matrix amorphous alloy as a reinforcement and takes an aluminum alloy as a matrix, and the aluminum matrix amorphous alloy is uniformly dispersed in the aluminum alloy. The preparation method is simple to operate, the temperature of a preparation process is low, and the composite can be prepared through a simple hot-pressed sintering process. The interface bonding strength of the aluminum matrix amorphous alloy and the aluminum alloy matrix is high, the interface state is good, and aluminum matrix amorphous alloy particles are uniformly distributed in the matrix and not easy to aggregate, so that the prepared composite is high in density and good in mechanical property, that is, the strength and the hardness are high.

Description

technical field [0001] The invention relates to an aluminum-based composite material reinforced by an amorphous alloy and a preparation method thereof, belonging to the technical field of composite material preparation. Background technique [0002] Particle reinforced aluminum matrix composites have excellent properties such as high specific strength, high specific modulus, wear resistance and good dimensional stability. As a new type of structural material, it has broad application prospects in aerospace, automotive, communication industries and other fields, and can also be used as an additive for advanced coatings. However, the poor shape and toughness of particle-reinforced aluminum matrix composites limit their application in structural materials. How to improve its shape and toughness has always been the goal pursued by researchers. [0003] Particle-reinforced aluminum matrix composites are composed of particle reinforcement and matrix. Currently, the widely used r...
