摘      要：Mechanism,condition and characteristics for the formation of the network structure in a group of Zr-Al-Ni-Cu bulk metallic glasses(BMGs) were *** results show that the constituent segregation and/or the symplastic growth would be the mechanisms for the formation of the cell structure in the present Zr-Al-Ni-Cu *** cell structure can be easily obtained for the glass forming alloys whose compositions locate nearby the eutectic *** shorter the distance is from the eutectic point,the larger the cell and the thicker the cell wall of the network structure will *** present investigation would provide useful information for the development of the BMG with the network structure.
