WebbIn binary systems, the peritectoid is the transformation of two solid phases in an alloy system, forming a new phase. These reactions happen in a similar way to peritectic transformations (see Peritectic), however, they only occur in the solid state. While, in a peritectic reaction, the melt and the phases separated from it take part, in the …
