Thermodynamics of the formation of composite material structures. A review

Abstract

Thermodynamics of the formation of composite material structures. A review Composite material structures at nano-, micro-, and meso-levels have been examined. The application of the Gibbs and Hill thermodynamics has allowed researchers to give the physical interpretation of the Laplace pressure for composite materials; to derive the thermodynamic functions describing the particles consolidation; to establish the new phenomenon, namely, metal melt imbibition (MMI), and to define its acting forces, to establish the criterion that allows to determine a direction of a liquid phase migration in a composite body, as well as to predict the final structure of composite materials. For the description of composite material structure, which forms under extreme conditions, it has been necessary to use the nonequilibrium thermodynamics. At the extreme conditions the Prigogine concept of local equilibrium is promising.

Liquid Phase Migration in Cemented Carbides – Experiments and Modelling

“…Experimental and theoretical studies of LPM during sintering of cemented carbides has been investigated previously by a number of different groups [11][12][13][14][15][16][17][18][19][20][21][22]. The experimental measurements of LPM in the literature are usually obtained by sintering of double pressed green bodies.…”
