Abstract
In this study the cold pressure welding between the aluminum powder and internal surface of aluminum tube was evaluated. The aluminum powder was compacted into the aluminum tube using the punch. The bond shear strength between the green compact disc and internal surface of tube at different amount of normal pressure of compaction was investigated. The effect of pressure on the cold bonding between the green compact disc and the inner surface of aluminum tube was investigated by SEM. The results of this study indicate that the discontinuity regions at the interface of the green compact disc and the inner surface of aluminum tube decreased and the bond shear strength increased with increasing compact pressure.
