Abstract
By using LAMMPS of the open source software, the micro-structures of Al30Co10 alloys were studied. Based on the average atomic volume, pair distribution function and bond-angle distribution functions, Honeycutt-Andersen (HA) bond-type index analysis shows that Al30Co10 alloy system begins to transform into a glass state with the temperature rapidly decreasing to 900 K. The process temperature is decreased from 900 K to 300 K, the radial distribution function g(r) the first peak height with increased, width as decreasing temperature, and the system is an amorphous alloy when second peak appears obvious splitting. The bond angle distribution function showed second peaks when the temperature dropped to 300 K, so that the alloy atoms become orderly. Meanwhile the 1551 bond pairs increase to 35% with decreasing temperature; it implies that the Al30Co10 alloy system can be well transformed into the glass state.
Highlights
With the long-range disorder and short-range characteristics of amorphous alloy, it is called the metallic glass (MGs)
The Pair distribution function (PDF) is defined by the probability of finding an atom in the spherical shell where particle i is taken as the center
By simulating the PDF of the liquid Al, we found that the PDF of the liquid Al are good agreement with the experimental data (Ref. 84) as shown in Figure 2; and calculating data represented by curve line and the circles represented experimental data
Summary
With the long-range disorder and short-range characteristics of amorphous alloy, it is called the metallic glass (MGs). The amorphous alloys are of great interest owing to their unique combination of high specific strength and ductility, good corrosion resistance and abrasive resistance, representing an intriguing class of potential structural materials [1]-[8]. (2015) Molecular Dynamics Simulation of Glass Forming Ability of Al30Co10 Amorphous Alloy. Among the large number of MGs materials, bulk Albased MGs have received increasing interest owing to their unique combination of high specific strength, low elastic modulus, good corrosion resistance, as well as low density, representing a promising engineering materials [5]-[7]. For the Al-based metallic glasses they are provided with low density and low elastic modulus, but can use the national defense and industrial applications, which have broad social value and economic value. We performed molecular dynamics (MD) simulations to study the glass formation of the liquid Al30Co10. It is hoped that more data will be provided for experiment by the molecular dynamics simulations to create the high temperature, high pressure and other extreme conditions
