抄録

  This study is aimed at examining the influence of ultrasound-assisted exothermic reaction and improved wettability on the incorporation of Al₂O₃ particles into molten aluminum alloy in melt stirring. The Al₂O₃ particles with premixed nickel powder were added to molten Al-5mass%Mg alloy and stirred at a rotation speed of 16.7rps at 1023K in a nitrogen atmosphere. The ultrasound was then transmitted to the molten aluminum alloy with a ceramic plate. The application of ultrasonic vibration to melt stirring not only improves the apparent wettability, but also helps to dissolve the nickel powder thoroughly into molten aluminum alloy. The exothermic reaction of the nickel aluminide formation is promoted by ultrasonic vibration applied. This exothermic reaction leads to a local temperature rise of the molten aluminum alloy, which also improves the wettability. The ultrasound-assisted exothermic reaction of the nickel aluminide formation contributes to an increase in the engulfed Al₂O₃ particles and also the preparation of pore-free composite slurry.
