In the present work,a novel hybrid composite composed of Ti-aluminide multi-layered part and continuous-SiCf-reinforced Ti-matrix part using a vacuum hot pressing/hot isostatic pressure (VHP/HIP) sintering process was synthesized.Then,the damage tolerance behavior of this hybrid composite was studied by tensile tests and in situ scanning electron microscopy (SEM) three-point bending tests.The results indicate that the mechanical properties and crack propagation of the hybrid composite are strongly influenced by the extrinsic toughness mechanism.In detail,the crack deflection of multi-layered composite and strengthening effect of SiCf-reinforced matrix composite are observed in the hybrid composite.Owing to the strengthening effect of continuous-SiCf-reinforced Ti-matrix part,the tensile strength of hybrid composite is much higher than that of neat Ti-aluminide multi-layered composite.Furthermore,it is found that the optimal damage tolerance ability is optimized when the notch position is located at the Ti-aluminide multi-layered part due to the crack deflection of multi-layered structure.
