| Abstract | A novel method to fabricate titanium aluminum carbides/alumina-laminated composites with weak interfaces was developed through heat treatment titanium aluminum carbides at 1300 degrees C and low oxygen partial pressure. The laminated composites consist of 0.5-mm-thick layers of titanium aluminum carbides joined together by the in situ formed Al2O3 interlayers. The interfaces are free of cracks or delaminations. These laminated materials exhibit better damage tolerance compared with the monolithic counterparts. Crack deflection along the Al2O3 interlayers was the main mechanism for the noncatastrophic failure. The fracture toughness was increased from 4.9 MPa center dot m1/2 for Ti2AlC to 7.3 MPa center dot m1/2 for Ti2AlC/Al2O3 composite and from 6.5 MPa center dot m1/2 for Ti3AlC2 to 10.4 MPa center dot m1/2 for Ti3AlC2/Al2O3 composite, and the work of fracture required to break samples was increased from 153 J/m2 for Ti2AlC to 676 J/m2 for Ti2AlC/Al2O3 composite and from 300 J/m2 for Ti3AlC2 to 1317 J/m2 for Ti3AlC2/Al2O3 composite. |
