Abstract Scope |
Through coupling of high gravity field and high temperature field of combustion synthesis, ZTA-TiC-Fe composite materials were prepared by high gravity combustion synthesis. The composite toughening of Al2O3-TiC ceramic materials was realized, including phase change toughening of tetragonal zirconia, zirconia fiber toughening and metal ductile phase toughening. The results showed that the fracture toughness of ZTA-TiC-Fe composite materials reached 9-11MPa·m1/2, which was 2-3 times higher than pure Al2O3-TiC commercial tool materials. |
