In the solid solution in an alloy sometimes, two phases which are already present interact at a fixed temperature to produce an entirely new phase. This is known as a peritectic transformation. Thus, the peritictic compound may showed the followings: * Depression of the yield point. O None. High strength and ductility. Isolated segregates scattered randomly in the matrix. Laminated layers as a result of the interaction of the two phases.
