METHOD FOR PREPARING ALUMINUM MATRIX COMPOSITE USING NO PRESSURE INFILTRATION

摘要

The present invention provides a method for preparing an aluminum matrix composite by infiltrating aluminum into a preform within a short period of time without a pressurization configuration using a special device as compared to the existing pressure infiltration method. According to one aspect of the present invention, provided is a method for preparing an aluminum matrix composite using pressureless infiltration, the method including: preparing a preform formed of a mixture of raw powders capable of forming ceramic through a combustion synthesis reaction; immersing the preform in an aluminum melt, in which a part of the preform is exposed to an external environment without being immersed in the aluminum me and infiltrating molten aluminum into the preform while causing a combustion synthesis reaction in the preform.
