Abstract

The present invention relates to a method for preparing aluminum/aluminum nitride or aluminum alloy/aluminum nitride composite materials. Aluminum or an aluminum alloy is melted at a high temperature of 2500°C or higher in a nitrogen (N2) gas atmosphere, in an ammonia (NH3) gas atmosphere, or in an atmosphere of a mixture of the two gases, so as to obtain high-temperature molten aluminum or induce a reaction between a portion of aluminum gas and nitrogen. Preferably, the aluminum or aluminum alloy is melted at the high temperature by arc melting. The method of the present invention involves melting the aluminum or aluminum alloy at a high temperature near a melting point, such that the composite materials may thus be quickly prepared, and aluminum/aluminum nitride or aluminum alloy/aluminum nitride composite materials that can be molded into a panel through cold-rolling may be prepared. In addition, the phase fraction of aluminum nitride may be adjusted by adjusting the arc-melting time, and thus aluminum/aluminum nitride or aluminum alloy/aluminum nitride composite materials having various ratios may be prepared.
