Paper Title:
The Mechanical Properties and Fracture Characteristics of AlN/Ti Laminated Composites
  Abstract

The AlN/Ti laminated composites were fabrication by plasma activated sintering. In the composites, the AlN layers were matrix layers and the Ti layers were as the toughening layers. The microstructure and mechanical properties were studied. XRD and SEM results showed that a new phase (TiN, Al5Ti2) in the layer interface was generated by reaction of AlN and Ti. The AlN/Ti interface bonding was strengthened by existing of the new phase, plastic deformation and bridging of ductile Ti phase. The crack propagation path would be extended by the flexuous pattern. Therefore, the fracture toughness of composites was improved obviously comparing with the monolithic AlN and the bending strength decreased a little.
