The Mechanical Properties of Al3Ti/6061 Al Composite Materials under the Magnetic Field

Reactants are the fluorine potassium titanate (K2TiF6), in situ synthesis of the melt reaction method and magnetic field is applied in the reaction ,under the same conditions, with no external field, under the magnetic field obtained Al3Ti/6061 composite materials for mechanical properties of contrast ;Scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis showed that: under the magnetic fields generated particles Al3Ti, smaller particles, the size is about 1-3μm diffuse evenly distributed in the aluminum matrix; Mechanical properties of composites research shows that tensile strength σb and elongation rate are improved with the magnetic field, Al3Ti/6061 composite materials tensile fracture surface shows that the fracture is a plastic fracture.
