Abstract
A method for fabricating a magnesium-based composite material, the method includes the steps of: (a) providing a magnesium-based melt and a plurality of carbon nanotubes, mixing the carbon nanotubes with the magnesium-based melt to achieve a mixture; (b) injecting the mixture into at least one mold to achieve a preform; and (c) extruding the preform to achieve the magnesium-based carbon nanotube composite material.

A method for fabricating a magnesium-based composite material, the method comprising the steps of
- (a) providing a magnesium-based melt and a plurality of carbon nanotubes, mixing the plurality of carbon nanotubes with the magnesium-based melt to achieve a mixture;
- (b) injecting the mixture into at least one mold, and cooling down and solidifying the mixture to room temperature to achieve at least one preform;
- and
- (c) extruding the at least one preform to achieve the magnesium-based carbon nanotube composite material;
- wherein step (c) further comprises substeps of:
- providing an extruding device having one exit;
- disposing the at least one preform in the extruding device;
- heating the at least one preform at a temperature in an approximate range from 300° C. to 450° C.;
- and
- extruding the at least one preform from the exit of the extruding device to achieve the magnesium-based carbon nanotube composite material.
