The Magnetic Chemical Preparation and Properties of the Al3Zr/6AO2 Aluminum Matrix Composites
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.
