Bianary phase sysstem
A phase diagram defined by multiple variables.
phase diagram defined by multiple variables.
Bianary Phase System
liquidus
the boarder between melt and melt+crystals, the melt composition follows this pattern
the boarder between melt and melt+crystals, the melt composition follows this pattern.
Liquidus
solidus
boundary between melt+ crysatls and solid solution, the crystal composition follows this pattern
boundary between melt+ crysatls and solid solution, the crystal composition folows this pattern
solidus
Tie line
Drawing a long line between the liquidus and solidus, where it intersects the liquidus is the current compositions in the melt at that temperatture, same for the crystals and the solidus
Drawing a long line between the liquidus and solidus, where it intersects the liquidus is the current compositions in the melt at that temperatture, same for the crystals and the solidus
Tiea line
eutectic
the temperature where all phases (melt and multiple crystals) are in equilibrium) heat cannot change untill enough energy has been put in/revoved
