Query: Lattice model for kinetics and grain size distribution in
  crystallization   We propose a simple, versatile and fast computational model tounderstand the
deviations from the well-known Kolmogorov-Johnson-Mehl-Avrami kinetic
theoryfound in metal recrystallization and amorphous semiconductor
crystallization. Our model describes in detail the kinetics of the
transformation and the grain size distribution of the product material, and is
in good agreement with the available experimental data. Other morphological and
kinetic features amenable of experimental observation are outlined, suggesting
new directions for further validation of the model.
