Peritectic reactions

A peritectic reaction occurs during the cooling of certain metal alloys, where a liquid metal reacts with an existing solid phase to form a new solid phase at a specific temperature. Imagine heating a mixture—at this temperature, part of the liquid combines with a solid to create a different solid, changing the material’s structure and properties. This process is important in materials science because it influences the final characteristics of metal alloys, like their strength or hardness, by controlling how different phases form and transform during cooling.
