      Eutectic reaction takes place at single temperature. It has degrees of freedom is zero '0'. Means transformation is at single temperature like in pure metals. So both cooling curves looks similar.

      The Eutectic alloy transformation occurs at constant temperature (Eutectic temperature).  The same goes for the pure metal transformation at constant temperature (Freezing temperature), during cooling. This can be seen from the Gibbs phase rule which has, F=0 in both the cases. This means that thereRead more

      The Eutectic alloy transformation occurs at constant temperature (Eutectic temperature).  The same goes for the pure metal transformation at constant temperature (Freezing temperature), during cooling.

      This can be seen from the Gibbs phase rule which has, F=0 in both the cases. This means that there is no independent variables during transformation and so it occurs at constant variable (temperature here).

      So we see that both Eutectic and pure metal have same cooling curve although eutectic is an alloy (doesn’t depend on composition).

    • BARC-16: Using Gibb’s Phase rule for a Binary Eutectic alloy, the maximum number of Phases that can co-exist at equilibrium are 4 (F=0, P = C+2 = 4). Then at the Eutetic point there should be 4 phases but we find only 3? Explain
