Viscosity of Fe–Mn–С Melts

The kinematic viscosity of Fe–Mn–C melts is measured with Mn contents of 5.0, 7.5, 10.0, 12.0, 15.0, 17.5, 20.0, and 25.0 wt % and C contents of 0.4 to 2.2 wt %. The kinematic viscosity is measured using damped torsional vibrations of a crucible with a melt upon the heating and subsequent cooling of the samples. The temperatures at which the characteristics of the viscous flow change and the liquid–liquid structural transition occurs in Fe–Mn–C melts are determined using the results from measuring the kinematic viscosity.
