Abstract
⺠Investigated glass crystallization over 4 orders of magnitude in heating rate. ⺠Low heating rates produce nanocrystals; high heating rates produce spherulites. ⺠Spherulites form at heating rates 1000x higher than the critical cooling rate. ⺠Spherulite formation activation energy is much lower than nanocrystallization. ⺠The number density of quenched-in nuclei during casting is â¼1014 mâ3.
