1. a solid mixture of two or more phases that forms from a single solid phase at a constant temperature and composition
Usage: metallurgy and materials science term

Examples

• The eutectoid transformation in steel occurs when austenite decomposes into ferrite and cementite.
• Engineers study eutectoid reactions to understand the microstructure of metal alloys.
• A eutectoid composition has a specific ratio of elements that determines its phase transformation behavior.
• The eutectoid point on a phase diagram marks the temperature at which the solid-state reaction occurs.
• Pearlite is a common eutectoid structure found in carbon steels.
