Abstract

Effects of aluminum content on microstructure and corrosion behavior of as cast Fe-Al-C alloys lightweight steel have been studied. The alloys were prepared by an induction furnace under an argon atmosphere. Microstructure of Fe-Al-C alloys containing 1.24, 3.3, 5.5, 7.5, and 9.05 wt-% aluminum showed ferrite and pearlite, where the higher levels of Al increases the amountof ferrite structures. Scanning electron microscope test results indicate the presence of aluminum carbides at the grain boundary of pearlite of Fe-Al-C alloy with 3.3% up to 9.05% Al. At 9.05% Al alloy structure nearly 100% ferrite, pearlite structures remaining are in the ferrite grain boundaries. Anincrease Al content resulted in significant improvement corrosion resistance in 0.5% NaCl solution.
