New Al-based amorphous alloys with high strength and good ductility were produced in an Al-Y-Ni system by liquid quenching. The tensile fracture strength(σf) and Vickers hardness reach 1140 MPa and 300 DPN for Al87Y8Ni5The specific strength defined by the ratio of σfto density is as high as 38, being much higher than that for conventional alloy steels. The high-strength Al-base amorphous alloys are expected to attract strong attention as a new type of high-strength material with low density.
