Explain the difference between a eutectic and eutectoid system, including the various regions in a eutectic phase diagram.
Binary system: - Eutectic = liquid <—> two solids - Eutectoid = solid <—> two other solids - Eutectic composition: comp. with minimum melting temperature; alternating layers of solid phases - Eutectic temperature: lowest T at which liquid occurs - Compositions below eutectic composition and above max pure solid concentration= hypoeutectic (eutectic comp with alpha regions) - Compositions above eutectic composition and below min pure solid concentration = hypereutectic (eutectic comp with beta regions)
