Phase boundaries of state diagrams of q-component systems as discontinuity surfaces of all second derivatives of the Gibbs equilibrium thermodynamic potential

The quantitative relationship has been determined between the slopes of single-and two-phase boundaries (PB) of state diagrams ( T- P composition) of q-component systems and discontinuities of the heat capacity, the compressibility, the thermal expansion coefficient of alloys and, generally, of all...

Description
Summary:The quantitative relationship has been determined between the slopes of single-and two-phase boundaries (PB) of state diagrams ( T- P composition) of q-component systems and discontinuities of the heat capacity, the compressibility, the thermal expansion coefficient of alloys and, generally, of all possible second derivatives of the Gibbs equilibrium thermodynamic potential (ETP).
