It is believed that the crystallization is composed oftwo processes: the diffusion of single atoms from amorphous state to crystallinesurface, and growth of ordered clusters and their shearing combination or shearingdeposition. Its availabilty has been satisfactorily tried to explain the experimentalresults of the structural configurature of the crystals formed in very early stage. Key words:  amorphous alloy      crystallization micromechanism      atomic diffusion      ordered cluster      shearing deposition      Received:  18 January 1991      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1991/V27/I1/115 1 卢柯,王景唐,金属学报,1991;27: B31 2 Gaskell P H.
