铁熔体快速冷却过程的分子动力学模拟
Molecular Dynamics Simulation of Rapid Cooling Process of Iron Melt
摘要
Abstract
Establishes 8×8×8 atomic box with LAMMPS,adopts EAM(embedded atom model) potential,to simulate large number iron atoms system. At first,heats up the system,then cool down the system under different cooling rate. Through molecular dynamics simulation,obtains energy-tem⁃perature curve,radial distribution function(RDF)and architecture. The results show that the crystal⁃lization temperature point is basically in coincident with the melting point when the cooling rate is lower than 1.8×1010 K/s;the product is amorphous when the cooling rate is higher than 1012 K/s;the degree of supercooling can reach 700 K;Fe single crystal can be prepared at cooling rate around 1011 K/s.关键词
