摘要： A method for producing multiphase particle-reinforced metal matrix composites is provided. The method is characterized by the combination of an in-situ reaction process under an external electromagnetic field and an in-situ crystallization process under an external electromagnetic field. A traveling wave magnetic field or a rotating magnetic field is employed during the in-situ reaction process, and a rotating magnetic field or a high frequency magnetic field is employed during the in-situ crystallization process. Said method can obtain homogeneous, gradient enhanced or surface reinforced composite materials.

摘要： A method of synthesizing metal matrix composite material by melt reaction in coupling magnetic field and ultrasonic field comprises: adjusting metal-base melt to the onset reaction temperature after refining, then adding reactants which generate reinforced particles by in-situ synthesis reaction with melt, keeping the reacted melt stand until it is cooled to casting temperature after the reaction, and then casting. Magnetic field and high-energy ultrasonic field are exerted simultaneously during the reaction. The magnetic field can be high-power pulse magnetic filed, high-frequency oscillating magnetic field or low-frequency alternating magnetic field. The metal matrix composite material produced by the above-mentioned method exhibits that reinforced particles are much finer, more uniformly distributed, and fit with metal matrix better.
