| Abstract: | Ti /TiAl gradient materials were prepared by field-activated pressure-assisted synthesis(FAPAS) process.The microstructure,phase composition and fracture morphography of the interface were analyzed by SEM and XRD.The bending strength of the sample was tested by three-point bending test.Meanwhile,finite element analysis with ANSYS code was used to calculate the mechanical properties such as residual stress and deformation.It was shown that fine TiAl particles were formed with FAPAS and maximum bending streng... |
