Abstract：ZrB/6063 nanocomposite was prepared by electromagnetic field technology using 6063 alloy as matrix material, and the relationship between the microstructure, mechanical properties and electromagnetic field was discussed. The results show that the diffraction peaks of aluminum matrix and ZrB structure are formed on the XRD diagram, and the intensity of the diffraction peaks increases with the addition of ZrB particles.When the electromagnetic frequency of electromagnetic field increases, the particles can form a more uniform distribution state, which improves the uniformity of particle size and greatly reduces the average size.When the electromagnetic frequency of the electromagnetic field increases, the mechanical properties of the composite increase obviously.When the electromagnetic frequency is 10 Hz, the tensile strength of the material is 358 MPa, the yield strength is 262 MPa, and the elongation is 24.7%, which increases by 38.8%, 67.9% and 32.8% respectively compared with the non-electromagnetic field.After increasing the electromagnetic field, more small dimples are formed in the tensile fracture area of the material, showing obvious dimple fracture characteristics.
