The formation of intermetallic compounds during interdiffusion of Mg-Al/Mg-Ce diffusion couples

Al-Ce intermetallic compounds (IMCs) formed in Mg-Al/Mg-Ce diffusion couples. During the whole diffusion process, Al was the dominant diffusing species, and it substituted for Mg atoms of the Mg-Ce substrate. Five Al-Ce IMCs of Al4Ce, Al11Ce3, Al3Ce, Al2Ce, and AlCe were formed via the reaction of Al and Ce.159
