Title:
A METHOD OF SYNTHESIZING METAL-BASED COMPOSITE MATERIAL BY MELT REACTION IN COUPLING MAGNETIC FIELD AND ULTRASONIC FIELD
Document Type and Number:
WIPO Patent Application WO/2010/051675
Kind Code:
A1
Abstract:
A method of synthesizing metal-based composite material by melt reaction in coupling magnetic field and ultrasonic field comprises: adjusting metal-base melt to the reaction starting 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 casting. Magnetic field and high-energy ultrasonic field are exerted simultaneously during the reaction. The magnetic field can be high-power pulse magnetic field, high-frequency oscillating magnetic field or low-frequency alternating magnetic field. The metal-based composite material produced by the above-mentioned method exhibits that reinforced particles are much finer, more uniformly distributed, and fit with metal matrix better.
