METHOD FOR MANUFACTURING ALUMINUM MATRIX COMPOSITE

PROBLEM TO BE SOLVED: To improve a production efficiency of an aluminum matrix composite, by placing crucibles used for manufacturing the aluminum matrix composite at maximum density, in a heating furnace used for manufacturing the aluminum matrix composite. SOLUTION: The method for manufacturing the aluminum matrix composite comprises: the first step of placing an aluminum alloy on a powder in the crucible; the second step of accommodating magnesium in a furnace along with the crucible; and the third step of obtaining the aluminum matrix composite by making a molten metal of an aluminum alloy penetrate among the powders by heating the inside of the furnace. The second step comprises attaching heat insulating materials 93 with different thicknesses of t1, t2 and t3 to each of the first to third crucibles 87 to 89; and placing the crucible 89 with a thick heat insulating material near to a heat source, and the crucible 87 with a thin heat insulating material more distant from the heat source than the crucible 89 with the thick heat insulating material. The formed heat-insulating material 93 has approximately the same height as the aluminum alloy 82 in the crucible has. COPYRIGHT: (C)2005,JPO&NCIPI
