Effect of Temperature on Solidification Rate Flashcards
1
Q
What is the atomic mobility and driving force for solidification just below the melting point?
A
ust below the melting point, the liquid has high atomic mobility and diffusivity, facilitating the movement and rearrangement of atoms. However, the driving force for solidification is low because the free energy difference between the solid and liquid phases is small.
2
Q
What is the solidification rate just below the melting point and why?
A
The solidification rate is moderate, driven by high atomic mobility but limited by a low driving force.
