Fast Cooling Solidification Eutectic Phase Diagram Theme Route By removing the time axis from the curves and replacing it with composition, the cooling curves indicate the temperatures of the solidus and liquidus for a given composition. this allows the solidus and liquidus to be plotted to produce the phase diagram: this page titled 12.5: interpretation of cooling curves is shared under a cc by nc sa. An essential point to remember in phase diagrams is that during normal or fast cooling, results may not be as expected in the diagram. both the theory and the experiments to construct phase diagrams rely on the assumption that the system is in equilibrium, which is rarely the case, as this only occurs properly when the system is cooled very slowly.
Fast Cooling Solidification Eutectic Phase Diagram Theme Route A eutectic system or eutectic mixture ( juːˈtɛktɪk yoo tek tik) [1] is a type of a homogeneous mixture that has a melting point lower than those of the constituents. [2] the lowest possible melting point over all of the mixing ratios of the constituents is called the eutectic temperature. on a phase diagram, the eutectic temperature is. Fig. 9.5 eutectic interface morphologies that can be obtained when the ! phase is non faceted and the " phase is either non faceted (left) or faceted (right). this is shown for two volume fractions of the " phase. the eutectic is growing in a thermal gradient perpendicular to the page.

Phase diagrams 2 eutectic reactions. the free energy curves and phase diagrams discussed in phase diagrams 1 were all for systems where the solid exists as a solution at all compositions and temperatures. in most real systems this is not the case. this is due to a positive Δ h m i x caused by unfavourable interactions between unlike.

Figure 8.9.1 8.9. 1: phase diagram of a two component system that exhibits an eutectic point. the unlabeled regions on the sides of the diagram indicate regions where one solid is so miscible in the other, that only a single phase solid forms. this is different than the “two phase solid” region where there are two distinct phases, meaning. The equilibrium solidification induces diffusion in the solid and liquid phases. the scheil model considers a deviation from the equilibrium solidification since it does not assume diffusion in the solid phase, but fast diffusion in the liquid phase. this solidification model is developed in a later section.
