Abstract：Al88Co4Y6Er2 amorphous alloys were prepared by meltspinning method Kinetics behavior of the Al88Co4Y6Er2 alloy was studied by the differential scanning calorimetry（DSC） With Ozawa′s methods, average activation energy for crystallization of amorphous Al88Co4Y6Er2 alloy are determined as 3706 kJ·mol-1The curves of relation of crystallized fraction x with temperature at different heating rates exhibited as a function of “S” shape A linear relationship was observed, which a value of Ea(x) decreased with crystallized fraction x
