For the ribbons obtained in 50-60 μm thick, the Al_(87)RE_8Ni_5 alloy was found to be an amorphous structure with no trace ofcrystallinity; whereas, Al_(92)RE_4Ni_4 alloy to be an amorphous phase in the wheel side, anamorphous structure containing finely dispersed α-Al particles, about 5 nm in diameter, inthe ribbon core, and a-Al micrograins structure, with the grain size of 15-25 nm, in the freeside. Amorphous Al_(87)RE_8Ni_5 and Al_2RE_4Ni_4 alloys all possess a very wide temperature spanof the supercooled liquid, △T_x=53 and 83 K respectively, and a distinct glass transition abili-ty with T_g / T_m=0.56 and 0.59 respectively.
