High strain rate behaviour of nano-quasicrystalline Al93Fe3Cr2Ti2 alloy and composites

Abstract We demonstrate the outstanding dynamic strength of nano-quasicrystalline Al 93 Fe 3 Cr 2 Ti 2 at.% alloy and composites. Unlike most crystalline Al alloys, this alloy exhibits substantial strain rate sensitivity and retains ductility at high strain rates. This opens new pathways for use in safety-critical materials requiring impact resistance.
