Ti and Ti alloy have gained widespread application in aerospace and automotive industries which are mainly ascribed to their desirable properties, such as light weight, high specific strength, good ductility and excellent corrosion resistance [11] and [12]. Moreover, Ti performs good physicochemical consistency with Al2O3[13], which makes it ideal candidate for the ductile reinforcement. Hence, Ti/Al2O3 composites are expected to be promising materials for aerospace, cutter, biology and many other applications owing to the combination of the high toughness of metal and the high strength and hardness of ceramic [14], [15] and [16]. However, relatively weak interfacial bonding between metal and ceramic leads to the unsatisfied hardness and strength, which limits the application in structural components. Recent investigations demonstrated that the interfacial bonding between Ti and Al2O3 was not firm enough, the mechanical properties of the composites were deteriorated due to the inherent brittleness of Ti–Al intermetallic compounds (TiAl and Ti3Al) which were caused by the strong interfacial reactions between Ti and Al2O3 at high temperature [17] and [18].
