Size distribution and growth rate of crystal nuclei near critical supercooling in small volumes

Original language description

Kinetic equations are numerically solved to determine the size distribution of crystal nuclei, F, formed in Ni droplets near critical supercooling. The maximum size of nuclei r max was determined from F as a function of time and the growth rate of the largest particles v=dr max /dt. In the sufficiently large volumes of the parent phase, the growth rate of particles v reaches some minimum value and then increases with time to the growth rate of the flat interface limit. In smaller volumes, only a certain maximum size of nuclei r max is reached, which quickly increases with supercooling. In consequence of depletion of the parent phase, the growth of the largest particles is stopped in small volumes. The growth of nuclei occurs only when the number of critical nuclei is sufficiently high.
