Analysis of Mechanical Properties of TiB2-TiC+Ni/TiAl/Ti Graded Materials Prepared by FAPAS

摘要：

TiB2-TiC+Ni/TiAl/Ti graded materials were prepared by field-activated pressure-assisted synthesis process (FAPAS) and the mechanical properties and residual stress were investigated. Shear fracture that occurs at the interface between the cermets and TiAl with the maximum shear strength of 85.88 MPa. The residual stress and deformation induced by the thermal effect of chemical reaction and Joule heat during the synthesis process were analyzed by nonlinear finite element simulation. It is demonstrated that the maximum equivalent residual stress locate in the transition layer between the ceramics and TiAl, consistent with the shear test result.
