The effect of the crystal structure of 35KhGF steel on the temperature dependence of the kinematic viscosity of the melt has been studied at temperatures of 1450–1780°C. The crystal structure of 35KhGF steel changes as a result of heat treatment, namely, normalizing and tempering. EBSD analysis is used to study the crystal structure of the steel. The kinematic viscosity of the liquid steel is measured...
In viscosimetric experiments on 32Г1 and 32Г2 liquid steel from oil and gas pipe, the temperature dependence of the kinematic viscosity is determined. The viscosity is measured by means of damping torsional oscillations of a crucible with melt in heating and subsequent cooling within the range 1450–1810°C. The results are interpreted in terms of the microheterogeneous structure of the metallic melts...
