- •
Effects of rotation speed on morphology of intermetallics, mechanical properties and interfacial temperature was studied.
- •
Joint efficiency, morphology of intermetallics and interfacial temperature reach critical points at the same rotation speed
- •
A maximum joint efficiency of 90% is achieved at 600 rpm.
- •
All dissimilar joints fractured along the boundary between intermetallics and TC4 matrix.
