Lecture
This lecture discusses binary systems, focusing on solid solutions and the phase diagrams of miscible systems. It covers the concept of degrees of freedom, the influence of temperature and pressure, and the phase equilibrium conditions. The instructor explains the solidification process, the phase diagram construction, and the rule for phase equilibrium in two-phase domains. The lecture also touches on the molar free enthalpy curves and the minimization of free enthalpy in solid and liquid phases.
