Critical radius of nucleus (from volume free energy) Solution

STEP 0: Pre-Calculation Summary

Formula Used

Critical radius of nucleus = -2*Surface free energy/Volume free energy
r_* = -2*𝛾/𝚫G_v
This formula uses 3 Variables

Variables Used

Critical radius of nucleus - (Measured in Meter) - Critical radius of nucleus is the minimum size of a stable nucleus formed during solidification.
Surface free energy - (Measured in Joule per Square Meter) - Surface free energy is the energy to create solid–liquid phase boundary during the solidification.
Volume free energy - (Measured in Joule per Cubic Meter) - Volume free energy is the free energy difference between the solid and liquid phases.

STEP 1: Convert Input(s) to Base Unit

Surface free energy: 0.2 Joule per Square Meter --> 0.2 Joule per Square Meter No Conversion Required
Volume free energy: -10000 Joule per Cubic Meter --> -10000 Joule per Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

r_* = -2*𝛾/𝚫G_v --> -2*0.2/(-10000)

Evaluating ... ...

r_* = 4E-05

Nucleation and growth

The progress of solidification involves two distinct stages: nucleation and growth. Nucleation involves the appearance of very small particles, or nuclei of the solid (often consisting of only a few hundred atoms), which are capable of growing. During the growth stage these nuclei increase in size, which results in the disappearance of some (or all) of the parent phase. The transformation reaches completion if the growth of these new phase particles is allowed to proceed until the equilibrium fraction is reached.
