A eutectic system or eutectic mixture is a homogeneous mixture that has a melting point lower than those of the constituents. 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 seen as the eutectic … See more The eutectic solidification is defined as follows: This type of reaction is an invariant reaction, because it is in thermal equilibrium; … See more Alloys Eutectic alloys have two or more materials and have a eutectic composition. When a non-eutectic alloy solidifies, its components solidify at different temperatures, exhibiting a plastic melting range. Conversely, … See more The composition and temperature of a eutectic can be calculated from enthalpy and entropy of fusion of each components.
