.... Peritectoid reactions are similar to peritectic reactions, except that one of the initial phases is liquid in a peritectic reaction. As in all invariant reactions, peritectoid reactions are reversible; that is, the α + β are recovered on heating the reaction product, γ. The reaction is: Solid  α...
