Abstract

The effects of the magnetic field on microstructures and wear properties of aluminum matrix composites are studied based on K2ZrF6-Al system. The results show that under the combination of magnetic field, melt can generate a forced exercise, which promotes melt dynamics changes in conditions, and thus playing the role of refined particles, changes in morphology and distribution. The SEM images of worn surface show that there is a serious adhesion and deformation within the 6A02 matrix alloy, which is adhesive wear and delamination abrasive, and the wear type of Al3Zr/6A02 composite materials is abrasive wear. Mechanical properties of Al3Zr/6A02 composites are greatly improved under the effect of the combination of magnetic field, and the tensile strength increases from 239.8MPa to 400.6MPa with a 67% increase. The area of plastic deformation is reduced, but is still ductile fracture.
