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.

Description

technical field [0001] The invention relates to an aluminum-based composite material reinforced by an iron-based 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 wi...
