中文摘要	Using spark plasma sintering technique, a bulk Al/sub 90/Mn /sub 9/Ce/sub 1/ alloy, reinforced by quasicrystal particles, has been sintered under the pressure of 50 MPa at 400 degrees C. The density and the compressive strength of the as-prepared bulk alloy are above 98% and 1000 MPa. respectively. It has been found that during the spark plasma sintering process, under the condition of large current, short sintering time and lower sintering temperature, the metastable icosahedron quasicrystal phase in primary powder particles is kept. And the strong discharge plasma among particles can decompose or break the oxide film on the primary powder's surface, resulting in the increment of their combination strength. So the as-prepared bulk alloy possesses high density and ultra-high strength.
