Fig. 2: Critical radii for nucleation in supercooled Fe–C alloys.
From: Constraining Earth’s core composition from inner core nucleation
Critical radii for liquid Fe1−xCx alloys between xC = 0.01 and xC = 0.1 (xC = 0.01 and xC = 0.03 cases are taken from Wilson et al.33), all at 360 GPa. rc is estimated from distributions of sub-critical nuclei. Uncertainties in rc are determined from the distributions of nuclei size at constant temperature (see Wilson et al.31 for details). Temperature is shown as supercooling (δT = Tm−T, where Tm is unique for each xC, Fig. 1).
