eutektoidisiin
Eutektoidisiin refers to a eutectoid reaction, a specific type of phase transformation that occurs in solid-state metallurgy. In a eutectoid reaction, a single solid phase transforms into two different solid phases upon cooling. This transformation is typically reversible, meaning the reverse reaction can occur upon heating.
The term "eutectoid" comes from the Greek words "eu" meaning good or well, and "tekton" meaning builder.
The composition at which the eutectoid reaction occurs is called the eutectoid composition. For the iron-carbon
