eutectoid reaction

A eutectoid reaction is a process where a single solid material transforms into two different solid phases simultaneously when cooled to a specific temperature. Imagine a metal alloy that, upon cooling, changes its internal structure into two distinct solid forms, creating a different combination of properties. This reaction occurs at a precise temperature and involves the internal arrangement of atoms shifting to produce two new solid microstructures. It’s similar to how ice transforms into frost and snowflakes as it cools, but in metals, this transformation influences their strength and hardness.
