Viscosity of the eutectic Fe_85-xCr₁₅C_x (x=10–17) melts

ABSTRACT

The kinematic viscosity measurements were carried out for liquid Fe_85-xCr₁₅C_x (x = 10–17at.%) alloys over a wide temperature range by the oscillating-cup method. The temperature dependences of viscosity of these liquid alloys within the heating and subsequent cooling modes are monotonically and well show the Arrhenius-like behaviour. Based on these temperature dependences concentration dependences of viscosity of Fe_85-xCr₁₅C_x (x = 10–17at.%) melts were calculated. A maximum on the concentration dependences of viscosity near the eutectic concentration of 14at.%C was found.
