Thermal Equilibrium Diagram (Leaving Cert Engineering): Flashcards

Graph showing temperature vs composition for binary metal alloys

Phase diagrams or constitutional diagrams

How temperature changes over time as alloy cools and solidifies

Cooling curves of different metal compositions

Upper boundary where solidification begins

Completely liquid form

Lower boundary where solidification is complete

Entirely solid

Area with both liquid and solid phases simultaneously

Between liquidus and solidus lines

Same temperature

Different temperatures

Difference between liquidus and solidus temperatures
