Abstract:
1. A method for making a metal-based nano-composite material, the method comprising steps of: providing a metal-based material in a semi-solid state; forming a semi-solid state mixture by mixing the metal-based material in the semi-solid state with nano-sized reinforcements; heating the semi-solid state mixture to a temperature above a liquidus temperature of the metal-based material, to achieve a liquid-metal-nano-sized reinforcement mixture; and ultrasonically processing the liquid-metal-nano-sized reinforcement mixture at a temperature above the liquidus temperature by conducting ultrasonic vibrations to the liquid-metal-nano-sized reinforcement mixture simultaneously along different directions; wherein the ultrasonically processing is processed by using a multi-dimension ultrasonic apparatus comprising:
