AbstractTiC particulate reinforced Ti6Al4V composites (Ti6Al4V/TiC/10p) have emerged in the last years due to its excellent properties combination
including superior speciﬁc strength as well as good high temperature properties. Joining is a an essential technology to implement
the use of these materials in industrial products. In the present study, solid-state diﬀusion bonding has been successfully applied to
the particle-reinforced composite producing high quality joints. Microstructural characterisation has been performed using scanning
electron microscopy (SEM) and the tensile properties have been determined using microﬂat tensile tests. Fractographic analysis has been
accomplished on the microﬂat tensile fracture surfaces in order to understand the damage mechanisms. The primary mechanism consists
of reinforcement fracture as a result of load transfer from the matrix to the particles followed by ﬁnal fracture by coalescence of microvoids
in the matrix.
