摘要
用θ -θ液态金属X射线衍射仪研究了液态纯铁在 15 5 0℃的结构 ,根据实验所得双体分布函数 ,利用Iida和Reynolds的公式对液态纯铁的动力粘度和表面张力进行了计算 .结果表明 ,液态纯铁在 15 5 0℃的动力粘度 η =6 .44mPa·s ,表面张力 γ =2 .0 4N/m ;根据公式 γ/ η =1516 kT/m ,液态纯铁的动力粘度和表面张力之间吻合较好 ;液体结构。
The liquid structure of pure iron at 1 550 ℃ was studied by θ-θ X ray high diffractometer. The dynamic viscosity of pure liquid iron, which was calculated from Iida formula, and the surface tension, which was obtained according to Reynolds formula, are 6.44 mPa·s and 2.04 N/m at 1 550℃, respectively. The dynamic viscosity and surface tension are in good agreement based on the formula γ/η=1516kT/m. There are correlations between liquid structure, dynamic viscosity and surface tension of liquid pure iron.
