3、ruded 6061-15wt% SiCp composite was joined by transient liquid phase diffusion (TLPD) bonding process in argon environment using 50-_mthick copper foil interlayer. The bonding was carried out at 560 C with two different applied pressures (0.1 and 0.2MPa) and five different holding times (20 min, 1,
4、2, 3 and 6 h). Kinetics of the bonding process was significantly accelerated in the presence of reinforcement (SiC). This acceleration is attributed to the increased solute diffusivity through defect-rich SiC particle/matrix interface and porosity. Adequate bond strength (90% of the original composi

This is very close to the reported highest bond strength achieved (92% of the original composite strength) for joining aluminium-based metal matrix composite by TLPD process in vacuum followed by isostatic pressing. The reje
