5种金属高压熔化曲线的理论计算
Theoretical calculations of high-pressure melting curves of five metals
摘要
Abstract
Ab-initio calculation method is employed to determine the potential functions and the unknown parameters in pair-potential-based mean filed model for metals.Using the mean fields constructed from the potential functions,the vibration free volumes of atoms of metals Al,Cu,Ni,Na,and K at melting points are evaluated.The results indicate that the widely used hypothesis that the ratio of vibration free volume to the primitive cell volume of atoms in melting curve is a constant,is not correct.We provide a ratio model which can be usd to obtain much more accurate results of melting curve.关键词
