The maximum tensile fracture strength and microhardness are as high as 760MPa and 294 DPN, respectively. As-quenched ribbons can be bent 180 deg without frac-turing. The dominant factors for formation of amorphous Al-La-Y-Ni (Fe) are the strongattractive interaction among Al, La, Y and a low melting temperature.
