eutectic reaction

A eutectic reaction occurs when a specific mixture of two or more materials cools and solidifies at a precise temperature, forming a distinct combination of solid phases simultaneously. It is a unique point in a material's phase diagram where liquid transforms directly into two different solid structures at once, resulting in a fine, uniform microstructure. This reaction is important in metallurgy and materials science because it influences properties like strength and melting behavior, enabling the design of alloys with specific characteristics by controlling their composition and cooling process.
