Abstract

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(σ_f) and Vickers hardness reach 1140 MPa and 300 DPN for Al₈₇Y₈Ni₅The specific strength defined by the ratio of σ_fto 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.
