Time-evolution of grain size distributions in random nucleation and growth crystallization processes

  journal={Physical Review B},
We study the time dependence of the grain size distribution $N(\mathbf{r},t)$ during crystallization of a $d$-dimensional solid. A partial differential equation, including a source term for nuclei and a growth law for grains, is solved analytically for any dimension $d$. We discuss solutions obtained for processes described by the Kolmogorov-Avrami-Mehl-Johnson model for random nucleation and growth (RNG). Nucleation and growth are set on the same footing, which leads to a time-dependent decay… Expand
