Dependences of Co—Si Melt Viscosity on Temperature and Concentration

Аннотация

The temperature and concentration dependences of the kinematic viscosity of Co-Si melts with a silicon content up to 54 at % have been studied. The temperature dependences of the viscosity obtained upon heating and cooling coincide and are well described by the Arrhenius equation. The concentration dependences of the viscosity and viscous-flow activation energy are nonmonotonic and dome-shaped with maximum values at a silicon content of 30–40 at %.
