Paper Title:
Defect and its Influence on Mechanical Property of Titanium Diboride-Copper Matrix Composite
  Abstract

The TiB2-40Cu-8Ni composite prepared by combustion synthesis is investigated. Both 2D digital radiography (DR) and 3D computed tomography (CT) are used to test the specimens nondestructively. The result shows that ceramic phase aggregation is the main defect. Then the mechanical properties of samples are assessed by means of three-point-bend test. It appears that mechanical properties are related with the distribution of TiB2 phase and Cu phase. The scanning electron microscope (SEM) is also used to observe the crack growth of the bending test sample.
