SESSION 20: Phase Diagram as a Tool of Materials Science


Symposium Polymer derived ceramics

The aim of the session is to discuss the key areas in material science and engineering based on phase equilibrium investigation. Thermodynamic calculations and experimental determinations produces sometimes phase diagrams with problems. The general Calphad produces phase diagrams by combining ab initio results, thermodynamic measurements data and phases modeling and lead to obtain a general view of the stabilities in the systems. Idea to assemble phase diagram from phase regions develops additional effective instrument for specialists in materials science and technology. In these diagrams all 3-phase regions are divided into the fragments with eutectic (eutectoid) and peritectic (peritectoid) reactions. Concentrations fields of invariant reactions permit to design microstructure of heterogeneous material. Competition of crystals with different dispersity produces alloys and ceramics which differ by microstructure. Any experimental or simulated section of phase diagram (isotherm and isopleth) may be corrected and verified. New technologies are offered to optimize experimental investigation.
