Abstract

Synopsis : Formation behaviors of aluminides at 450°C in the interfacial region between M sheets (M=Au, Cu, Fe, Mn, and Ni) and molten 0.2 wt.%Al-Zn were investigated by simple dipping method of M sheets into molten Al-Zn bath. In the Fe and Ni sheets dipped for 60 s, aluminides were formed in the diffusion zone, while not observed in the Au, Cu and Mn sheets. These results were discussed in the view points of the chemical interactions between M and Al, the up-hill diffusion of Al induced by concentration gradient of M element in liquid Zn, and the relative stability of M-Al intermetallic compounds to M-Zn based intermetallic compounds.
