Eutectic and peritectic reactions

Eutectic and peritectic reactions are processes that occur in mixtures of substances, particularly in metallurgy. A eutectic reaction happens when a liquid solution cools and solidifies into two distinct solid phases at a specific temperature and composition. This results in a finely mixed structure. In contrast, a peritectic reaction occurs when a solid and a liquid merge upon cooling to form a different solid with a different composition. These reactions are important in materials science and engineering as they influence the properties and behaviors of alloys and other materials during cooling and solidification.
