Abstract: A method for fabricating a magnesium-based alloy includes the steps of: (a) mixing a number of carbon nanotubes with a number of magnesium particles; (b) heating the mixture in a protective gas to achieve a semi-solid-state paste; (c) stirring the semi-solid-paste using an electromagnetic stirring force to disperse the carbon nanotubes into the paste; (d) injecting the semi-solid-state paste into a die; and (e) cooling the semi-solid-state paste to achieve a magnesium-based alloy. An apparatus for fabricating the magnesium-based alloy includes a transferring device, a thixomolding machine, and an electromagnetic stirring device. The transferring device includes a feed inlet. The thixomolding machine includes a heating barrel having two ends, a nozzle disposed at a first end thereof, and an material input positioned at a second end thereof. The electromagnetic stirring device includes an electromagnetic induction coil disposed on an outer wall of the heating barrel.

Abstract: The present invention relates to a magnesium-based composite material includes at least two magnesium-based metallic layers; and at least one magnesium-based composite layer respectively sandwiched by the at least two magnesium-based metallic layers. The present invention also relates to a method for fabricating a magnesium-based composite material, the method includes the steps of: (a) providing at least two magnesium-based plates; (b) providing a plurality of nanoscale reinforcements; (c) sandwiching the nanoscale reinforcements between the at least two magnesium-based plates to form a preform; and (d) hot pressing the preform to achieve the magnesium-based composite material.

Abstract: An apparatus for fabrication of a magnesium-based carbon nanotube composite material, the apparatus includes a thixomolding machine, and a feeding device. The thixomolding machine includes a heating barrel, a feeding inlet, a nozzle, a heating portion, and a plunger. The heating barrel includes a first end and a second end.
