Question
sir,

i want to know the difference between a eutectic alloy and congruent melting alloy( which is sometimes called as the pseudo-eutectic alloy). how do they differ?

Answer
In eutectic solidification, the liquid phase solidifies by decomposition into two solid phases of different compositions, one solid phase having a lower alloy content than the parent liquid and the other solid phase having more alloy content than the parent liquid:

L-->S1+S2

During congruent solidification (melting), on the other hand, the liquid phase solidifies to a single solid phase of the same composition as the liquid (no alloying element partitioning):

L-->S
