Abstract
Simultaneous sintering and bonding of pure aluminum powder and mild steel (SS400) bar were carried out by the pulsed electric-current sintering (PECS) process. Relative density of sintered aluminum was about 99.3 to 100%. An intermetallic compound layer (FeAl_3) was formed at the bonded interface in Al/SS400. Thickness of the layer increased with an increase in bonding temperature and holding time. The tensile strength of the bonded joint was about 70MPa at 773 and 823K under 98MPa pressure.
