中文摘要	Based on the empirical embedded-atom method, the molecular dynamics studies of the local orientational orders and structures of liquid and amorphous solid of FCC-type metals Au and Ni are performed. During the rapid solidification, the amorphous structures can be obtained and their amorphous transition temperatures are determined. The icosahedral ordering and the short-range ordering are enhanced, and FCC-type as well as HCP-type ordering changes slightly during the quench of Au and Ni. In the mean time, the BCC-type ordering of Au is hardly enhanced, but that of Ni is weakened. The results of the simulation also indicate that the diffusion coefficients in Au and Ni decrease rapidly with decreasing temperature above their glass transition temperatures.
