%X The ribbons of amorphous Al-La-Y-Ni (Fe) quarternary alloys, prepared bysingle-roller melt spinning technique under vacuum, superior strength, ductility and thermalstability may be achieved when the alloy contains 85-90 at.-% Al and less than10at.-% La+Y. 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.
