| Abstract: | The mechanical properties and microstructure of Al2O3/SiC(nano) ZrO2 (3Y) composites were studied. The possibility of the ZrO2(t) transformation toughened together with nano-partical toughened action were discussed. The result indicated that the addition of opportune amount nano-ZrO2(3Y) particle had obvious effect on the material microstructure and improved the mechanical properties of materials. |
