摘要: In this paper, we investigated the structural properties of metallic glasses (MGs). We emphasized our study on monatomic Al and binary TiAl3 systems. The calculations are performed by using molecular dynamics (MD) simulation based semi-empirical many-body potentials derived from embedded atom method. structure is analyzed radial distribution function (RDF), common neighbor analysis (CNA) coordination numbers (CNs). Our results demonstrated that it possible to form MGs in both systems upon fast cooling liquid state. This confirmed fact system energy and/or volume during stage decrease continuously with a slight change atomic scale RDF, CNA CN analyzing techniques. Furthermore, specific shows under same conditions, icosahedral structures appeared more abundant than pure Al. Implications these findings discussed.
