The effect of the gradual substitution of Ti by Al on glass forming ability and structure in the Cu52Zr40Ti8-xAlx(x=0, 2, 4, 6, 8) alloys was studied by using XRD, DSC and SEM. Furthermor, the nanocrystallization behavior of the amorphous alloys also was studied by annealing method. The result indicates that the glass-forming ability and thermal stability is decreased with the increasing of the content of Al. On the other hand, the nano crystals with diameter of 50 - 100 nm were all observed when the five amorphous samples were annealed at 650 K for 1h.
