Formation of aluminium carbide by cast iron and liquid aluminium interaction

Al2MgC2 and AlFe3C formation in AZ91 Mg alloy melted in Fe-C crucibles

“…Similar results have been reported in studies of Fe-C alloys hot dipped in liquid Al and Albased alloys at temperatures in the range 600-950 °C [41][42][43][44], although the main intermetallic reaction layer is η-Al5Fe2 (instead of B2-AlFe) in those more Al-rich systems. In Kwak et al's experiment [44], Fe-0.23C steel was hot dipped in liquid Al-7Mn alloy at 773 °C up to 120 s and a -AlFe3C layer was found between η-Al5Fe2 and A2-α-Fe.…”

In Sidhu et al's experiment [42], cast iron (~3 wt.% C) was hot dipped in liquid Al (99.97 wt.%) at 950 °C for 2 h and a -AlFe3C layer was formed between B2-AlFe (a thin layer adjacent to η-Al5Fe2) and A2-α-Fe.…”

Review on corrosion resistance of mild steels in liquid aluminum

“…In this paper, based on the previous researches [22][23][24][25][26][27][28] on the reactions of mild steels J o u r n a l P r e -p r o o f 3 in liquid aluminum, especially the formation and growth of IMCs during the reaction process, the characteristics, formation and growth mechanisms and Fe-Al IMCs kinetics analysis, as well as the improvement approaches were summarized and discussed systematically. More importantly, the critical factors affecting the corrosion resistance of mild steels in liquid aluminum were unraveled and analyzed, which may provide a guidance for the development of corrosion resistant materials.…”

“…Studies [10,25,44,[72][73][74][75][76] have shown that secondary phases such as graphite, IMCs, ceramics, etc. possess extremely little solubility in liquid aluminum and hardly react with the liquid aluminum.…”

“…Balloy et al [2,10,25,76] suggested that the presence of C-rich phase (Al4C3) and J o u r n a l P r e -p r o o f 14 graphite can effectively enhance the corrosion resistance of ferrous alloys in liquid aluminum because they are able to act as an efficient barrier to the Al diffusion. Fig.…”
