Nanoparticles Size in Fe_73.5Cu₁Mo₃Si_13.5B₉ Melt

Abstract:

The size of the nanoparticles participating in the viscous flow and the diffusion coefficient were calculated using statistical mechanical theory of absolute reaction rates and the Arrhenius equation. As experimental data, temperature dependence of the kinematic viscosity and density of Fe_73.5Cu₁Mo₃Si_13.5B₉ melt was used. At a temperature of 1600 K, after the melt is overheated above the critical temperature T_k = 1770 K, the nanoparticles size decreases from 0.92 to 0.47 nm, and the diffusion coefficient increases from 2.4·10^-10 to 4.5·10^-10 m²·s^-1.
