| Abstract: | Adding 15% ZrO 2 and 15% ZrO 2+22% SiCu to Al 2O 3/TiC ceramic material,got bending strengty and fracture toughness of ATE and ATZS complex material are increased by a factor of 2 times compared with Al 2O 3/TiC matrix material and the data separately are up to 989 MPa,10 96 MPam 1/2 and 1094 MPa,11 26 MPam 1/2 .Through observation to fracture surface and microstructure of this material used of SER and TEM,the result states the tougening mechanism of ATZ and ATZS complex material is ZrO 2 phase toughened and the interface striped. |
