WebMar 14, 2024 · A eutectoid reaction is a chemical reaction in which a solid transforms into two other solid phases at the same time upon cooling. This is a three-phase reaction … Web· The Peritectoid invariant reaction involves two solids reacting to form a single solid phase: γ → α + β. Reactions of this type are found in the copper-zinc ( brass ) binary system. · Because solid state diffusion is involved in the phase change reactions, these processes are slower than those in which a liquid phase is present.
