摘要	Isothermal nanocrystallization of Zr55Al10Ni5Cu30 bulk amorphous alloy near the glass transition temperature has been investigated by DSC, XRD and TEM. Nanocrystals with a size of 20 nm precipitated from the amorphous matrix when annealed at 420 degreesC for 5 h, and homogeneous medium-range order (structure on the 1-2 nm scale) appeared in the amorphous matrix. As annealed at 420 degreesC for 10 h, the nanocrystals have a size of 20-50 nm and a volume fraction of about 40%. The annealing treatment at 420 degreesC for 20 h led to the completion of crystallization of the amorphous structure, but the crystalline phases have a size of 50 nm, justly as the sample treated for 5 h. The crystallization of Zr55Al10Ni5Cu30 bulk amorphous alloy at 420 degreesC is through a process of amorphous --> amorphous with medium-range order + metastable phases --> metastable phases.
