On the fabricability of a composite material containing the FCC matrix with embedded ductile B2 intermetallics

An imaginary composite material containing a ductile Al-rich FCC matrix with embedded particles of ductile RMg intermetallics (R is a rare-earth metal) may possess high strength and formability thus making it suitable as a replacement for steel in automotive applications. Although different fabrications routes can be explored, a direct-chill casting is likely least expensive of them. A crucial question is whether it is possible to find such a …
